+Installation Instructions
+*************************
+
+Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005 Free
+Software Foundation, Inc.
+
+This file is free documentation; the Free Software Foundation gives
+unlimited permission to copy, distribute and modify it.
+
+Basic Installation
+==================
+
+These are generic installation instructions.
+
+   The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions.  Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+   It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring.  (Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.)
+
+   If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release.  If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+   The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'.  You only need
+`configure.ac' if you want to change it or regenerate `configure' using
+a newer version of `autoconf'.
+
+The simplest way to compile this package is:
+
+  1. `cd' to the directory containing the package's source code and type
+     `./configure' to configure the package for your system.  If you're
+     using `csh' on an old version of System V, you might need to type
+     `sh ./configure' instead to prevent `csh' from trying to execute
+     `configure' itself.
+
+     Running `configure' takes awhile.  While running, it prints some
+     messages telling which features it is checking for.
+
+  2. Type `make' to compile the package.
+
+  3. Optionally, type `make check' to run any self-tests that come with
+     the package.
+
+  4. Type `make install' to install the programs and any data files and
+     documentation.
+
+  5. You can remove the program binaries and object files from the
+     source code directory by typing `make clean'.  To also remove the
+     files that `configure' created (so you can compile the package for
+     a different kind of computer), type `make distclean'.  There is
+     also a `make maintainer-clean' target, but that is intended mainly
+     for the package's developers.  If you use it, you may have to get
+     all sorts of other programs in order to regenerate files that came
+     with the distribution.
+
+Compilers and Options
+=====================
+
+Some systems require unusual options for compilation or linking that the
+`configure' script does not know about.  Run `./configure --help' for
+details on some of the pertinent environment variables.
+
+   You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment.  Here
+is an example:
+
+     ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix
+
+   *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you must use a version of `make' that
+supports the `VPATH' variable, such as GNU `make'.  `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script.  `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+   If you have to use a `make' that does not support the `VPATH'
+variable, you have to compile the package for one architecture at a
+time in the source code directory.  After you have installed the
+package for one architecture, use `make distclean' before reconfiguring
+for another architecture.
+
+Installation Names
+==================
+
+By default, `make install' installs the package's commands under
+`/usr/local/bin', include files under `/usr/local/include', etc.  You
+can specify an installation prefix other than `/usr/local' by giving
+`configure' the option `--prefix=PREFIX'.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+pass the option `--exec-prefix=PREFIX' to `configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+   In addition, if you use an unusual directory layout you can give
+options like `--bindir=DIR' to specify different values for particular
+kinds of files.  Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+   If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System).  The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+   For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+There may be some features `configure' cannot figure out automatically,
+but needs to determine by the type of machine the package will run on.
+Usually, assuming the package is built to be run on the _same_
+architectures, `configure' can figure that out, but if it prints a
+message saying it cannot guess the machine type, give it the
+`--build=TYPE' option.  TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+     CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+     OS KERNEL-OS
+
+   See the file `config.sub' for the possible values of each field.  If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+   If you are _building_ compiler tools for cross-compiling, you should
+use the option `--target=TYPE' to select the type of system they will
+produce code for.
+
+   If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+If you want to set default values for `configure' scripts to share, you
+can create a site shell script called `config.site' that gives default
+values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists.  Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+Variables not defined in a site shell script can be set in the
+environment passed to `configure'.  However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost.  In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'.  For example:
+
+     ./configure CC=/usr/local2/bin/gcc
+
+causes the specified `gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).  Here is a another example:
+
+     /bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+Here the `CONFIG_SHELL=/bin/bash' operand causes subsequent
+configuration-related scripts to be executed by `/bin/bash'.
+
+`configure' Invocation
+======================
+
+`configure' recognizes the following options to control how it operates.
+
+`--help'
+`-h'
+     Print a summary of the options to `configure', and exit.
+
+`--version'
+`-V'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`--cache-file=FILE'
+     Enable the cache: use and save the results of the tests in FILE,
+     traditionally `config.cache'.  FILE defaults to `/dev/null' to
+     disable caching.
+
+`--config-cache'
+`-C'
+     Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+     Do not print messages saying which checks are being made.  To
+     suppress all normal output, redirect it to `/dev/null' (any error
+     messages will still be shown).
+
+`--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     `configure' can determine that directory automatically.
+
+`configure' also accepts some other, not widely useful, options.  Run
+`configure --help' for more details.

+		  GNU LESSER GENERAL PUBLIC LICENSE
+		       Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+     51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+		  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+  
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+			    NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Lesser General Public
+    License as published by the Free Software Foundation; either
+    version 2.1 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+    Lesser General Public License for more details.
+
+    You should have received a copy of the GNU Lesser General Public
+    License along with this library; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the
+  library `Frob' (a library for tweaking knobs) written by James Random Hacker.
+
+  <signature of Ty Coon>, 1 April 1990

+
+That's all there is to it!

+gst-plugin is a template for writing your own GStreamer plug-in.
+
+The code is deliberately kept simple so that you quickly understand the basics
+of how to set up autotools and your source tree.
+
+This template demonstrates :
+- what to do in autogen.sh
+- how to setup configure.ac (your package name and version, GStreamer flags)
+- how to setup your source dir
+- what to put in Makefile.am
+
+More features might get added to this template later on.

+2008-03-07  Edward Hervey  <edward.hervey@collabora.co.uk>
+
+	* m4/gtk-doc.m4: (GTK_DOC_CHECK): 
+	The previous commit to this file by Stefan Kost mentionned checking for
+	SED, but NOT checking for gtkdoc-check (wth is that doing there ??).
+	Therefore, removing the check for gtkdoc-check
+
+2008-03-03  David Schleef  <ds@schleef.org>
+
+	* m4/ax_create_stdint_h.m4: Oops, checked in the wrong copy of
+	  this file.  (Update from upstream)
+
+2008-03-03  David Schleef  <ds@schleef.org>
+
+	* m4/ax_create_stdint_h.m4:  Update from upstream.  Fixes a bug
+	  compiling with MSVC.
+
+2008-03-03  Edward Hervey  <edward.hervey@collabora.co.uk>
+
+	* m4/pkg.m4:
+	Allow override of pkg-config results, as proposed by configure --help.
+	This is in fact just a backport from upstream pkg.m4.
+	Fixes #518892
+
+2008-03-03  Peter Kjellerstedt  <pkj@axis.com>
+
+	* ChangeLog:
+	Changelog surgery of my previous commit to add bugzilla reference.
+	* m4/gst-args.m4:
+	Add AG_GST_CHECK_PLUGIN and AG_GST_DISABLE_PLUGIN to make it easier
+	to include and exclude plug-ins without external references, i.e.,
+	plug-ins listed in GST_PLUGINS_SELECTED. (#498222)
+
+2008-03-03  Sebastian Dröge  <slomo@circular-chaos.org>
+
+	* gst.supp:
+	Add another glibc suppression.
+
+2008-02-29  Peter Kjellerstedt  <pkj@axis.com>
+
+	* m4/gst-feature.m4:
+	Make the comment before defines generated via AG_GST_CHECK_FEATURE
+	look nicer. (#498222)
+
+2008-02-26  Jan Schmidt  <jan.schmidt@sun.com>
+
+	* m4/Makefile.am:
+	* m4/as-gcc-inline-assembly.m4:
+	Add Dave Schleef's GCC inline assembly detection macro
+	for using in gst-plugins-good in the goom 2k4 plugin.
+
+2008-02-25  Andy Wingo  <wingo@pobox.com>
+
+	* gst-autogen.sh: Instead of only passing certain arguments to
+	configure, pass anything that we didn't handle. Much friendlier.
+	Fixes #34412.
+
+2008-02-23  Jan Schmidt  <Jan.Schmidt@sun.com>
+
+	* m4/gst-error.m4:
+	Store the detected compiler flags into ERROR_CFLAGS rather than
+	ERROR_CXXFLAGS, and use the macro that checks the C compiler, not
+	the C++ one.
+
+2008-02-23  Tim-Philipp Müller  <tim at centricular dot net>
+
+	* m4/gst-error.m4:
+	  Reflow checks for additional warning flags so they're not
+	  nested, which fixes the result reporting in the configure
+	  output.
+
+2008-02-22  Tim-Philipp Müller  <tim at centricular dot net>
+
+	* m4/as-compiler-flag.m4:
+	  Add AS_CXX_COMPILER_FLAG
+
+	* m4/gst-error.m4:
+	  Add AG_GST_SET_ERROR_CXXFLAGS (Forte bits need testing)
+
+2008-02-22  Tim-Philipp Müller  <tim at centricular dot net>
+
+	* gtk-doc-plugins.mak:
+	  Add 'check-inspected-versions' target; this helps identify
+	  files that should have been removed or where the version
+	  number should (ideally) be updated before a release
+	  (which doesn't happen automatically if the releaser doesn't
+	  build that plugin locally). Not adding at a distcheck hook
+	  yet though, because it's not really that important and would
+	  probably also be a problem on buildbots.
+
+2008-02-22  Sebastian Dröge  <slomo@circular-chaos.org>
+
+	* gst.supp:
+	Add even more glibc 2.7 suppressions.
+
+2008-02-22  Sebastian Dröge  <slomo@circular-chaos.org>
+
+	* gst.supp:
+	Add another suppression for GLib caching some values after
+	the first call.
+
+2008-02-12  Sebastian Dröge  <slomo@circular-chaos.org>
+
+	Patch by:
+	  Tim Mooney <mooney at dogbert dot cc dot ndsu dot nodak dot edu>
+
+	* m4/gst-error.m4:
+	Use no%E_MACRO_REDEFINED on Solaris to prevent compiler warnings.
+	Fixes bug #515905.
+
+2008-02-11  Sebastian Dröge  <slomo@circular-chaos.org>
+
+	* gst.supp:
+	Add a few more glibc 2.7 suppressions to make the avisubtitle unit
+	test valgrind clean. Fixes bug #515703.
+
+2008-02-08  Stefan Kost  <ensonic@users.sf.net>
+
+	* ChangeLog:
+	  Changelog surgery for last commit.
+
+2008-02-08  Stefan Kost  <ensonic@users.sf.net>
+
+	* m4/gtk-doc.m4:
+	  Conditionally check for SED. Also sync a bit with upstream macro.
+
+2008-02-08  Stefan Kost  <ensonic@users.sf.net>
+
+	* gtk-doc-plugins.mak:
+	* gtk-doc.mak:
+	  Use '$(SED)' instead of 'sed'. Don't use -i for in-place as its gnu
+	  only, move to a temp file instead.
+
+2008-02-06  Stefan Kost  <ensonic@users.sf.net>
+
+	* gtk-doc-plugins.mak:
+	* gtk-doc.mak:
+	 As our docs are versioned, we need to patch the index.sgml file to have
+	 correct paths there, unless we also want to fork gtk-doc's xsl (which
+	 we don't). This hopefully fixes xrefs between modules.
+
+2008-02-02  Sebastian Dröge  <slomo@circular-chaos.org>
+
+	* m4/gst-feature.m4:
+	Use printf instead of echo as "echo -e" isn't POSIX and doesn't work
+	with strict POSIX shells like tcsh or dash and also not every platform
+	has a /bin/echo that supports it.
+
+2008-01-24  Stefan Kost  <ensonic@users.sf.net>
+
+	* ChangeLog:
+	  ChangeLog surgery.
+
+	* gstdoc-scangobj:
+	  Sync the object scanner with gtk-doc fixes. Update args and hierarchy
+	  files.
+
+2008-01-20  Sebastian Dröge  <slomo@circular-chaos.org>
+
+	* check.mak:
+	* coverage/lcov.mak:
+	* gtk-doc-plugins.mak:
+	* release.mak:
+	Use $(MAKE) instead of make to fix the build if GNU make is called
+	something else on the system.
+	
+	* m4/as-docbook.m4:
+	Fix path for docbook.xsl if we have no /etc/xml/catalog and add a
+	docbook-xsl search path for FreeBSD.
+
+2008-01-18  Sebastian Dröge  <slomo@circular-chaos.org>
+
+	* gst.supp:
+	Add a suppression for a glibc bug:
+	http://valgrind.org/docs/manual/faq.html#faq.exit_errors>
+
+2008-01-18  Sebastian Dröge  <slomo@circular-chaos.org>
+
+	* gst.supp:
+	Add some more glibc 2.7 suppressions and make the GLib suppressions
+	for the home/tmp/etc directory caching a bit more generic.
+
+2008-01-18  Sebastian Dröge  <slomo@circular-chaos.org>
+
+	* gst.supp:
+	Add some glibc 2.7 supressions as found on Debian/unstable.
+
+2008-01-14  Jan Schmidt  <jan.schmidt@sun.com>
+
+	* download-translations:
+	Apparently I have problems with leaving things commented out when
+	I edit shell scripts.
+
+2008-01-12  Jan Schmidt  <Jan.Schmidt@sun.com>
+
+	* download-translations:
+	Remove bash-isms
+
+2008-01-12  Jan Schmidt  <Jan.Schmidt@sun.com>
+
+	* check-exports:
+	Restore the cleanup rm of our tmp file which I didn't mean to leave 
+	commented out.
+
+2008-01-12  Jan Schmidt  <Jan.Schmidt@sun.com>
+
+	* check-exports:
+	  Fixes to make check-export work on both Solaris and Linux
+
+	* m4/gst-error.m4:
+	  Disable extra warning category (argument mismatch) as an error
+	  on Forte, as it prevents the libcheck fail_if macros from compiling.
+
+	* win32.mak:
+	  Substitute the GStreamer version so things will keep working in 0.11
+
+2008-01-11  Tim-Philipp Müller  <tim at centricular dot net>
+
+	Patch by: Peter Kjellerstedt <pkj axis com>
+
+	* m4/gst-glib2.m4:
+	* m4/gst-libxml2.m4:
+	  Improve/fix output from configure if either glib-2.0 or
+	  libxml2 are not installed (#498222).
+
+2008-01-09  Stefan Kost  <ensonic@users.sf.net>
+
+	* coverage/lcov.mak:
+	  Update coverage make-rules: use them conditionaly, use libtool mode
+	  and use lcov to cleanup.
+
+2007-12-18  Sebastian Dröge  <slomo@circular-chaos.org>
+
+	* glib-gen.mak:
+	  Also use #include "header" instead of #include <header> for the
+	  headers that were used to generate the source files for the same
+	  reason as below.
+
+	  Remove whitespace before #include.
+
+2007-12-18  Sebastian Dröge  <slomo@circular-chaos.org>
+
+	* glib-gen.mak:
+	  Use #include "header" instead of #include <header> for the generated
+	  enum C files as the file will always be in the same directory and
+	  some compilers seem to be a bit strict about that unless . is added
+	  to the include path.
+
+	  Include all headers that were used to generate the source files in
+	  the C file as they're used there.
+
+2007-12-17  Tim-Philipp Müller  <tim at centricular dot net>
+
+	* win32.mak: (win32), (win32defs), (win32crlf):
+	  Make check for CR LF in Visual C++ 6.0 project files
+	  work, based on patch by David Schleef (#496722, #393626).
+	
+2007-12-17  Tim-Philipp Müller  <tim at centricular dot net>
+
+	* Makefile.am:
+	  Don't forget to dist the new win32.mak.
+
+2007-12-17  Tim-Philipp Müller  <tim at centricular dot net>
+
+	* win32.mak: (win32), (win32defs):
+	  Move common win32 Makefile foo into this new file.
+
+2007-12-15  Stefan Kost  <ensonic@users.sf.net>
+
+	* gtk-doc-plugins.mak:
+	* gtk-doc.mak:
+	  We should have never forked this that much :/.
+
+2007-12-13  Tim-Philipp Müller  <tim at centricular dot net>
+
+	* check-exports:
+	  Fix build on the ppc64 build bot.
+
+2007-12-13  Tim-Philipp Müller  <tim at centricular dot net>
+
+	* check-exports:
+	  Suppress more unintentional exports (too much hassle to rename them,
+	  since the win32 project files would need changing too).
+
+2007-12-12  Tim-Philipp Müller  <tim at centricular dot net>
+
+	* Makefile.am:
+	  check-exports should be disted.
+
+2007-12-12  Tim-Philipp Müller  <tim at centricular dot net>
+
+	* check-exports:
+	  Add quick'n'dirty script to check the exported symbols of a library
+	  against the symbols in the corresponding .def file (#493983). Based
+	  on script by Ole André Vadla Ravnås.
+
+2007-11-06  Jan Schmidt  <jan.schmidt@sun.com>
+
+	* gtk-doc-plugins.mak:
+	Fix distcheck by making sure the types files are treated like the
+	other gtkdoc-scangobj generated files.
+
+2007-09-21  Sebastian Dröge  <slomo@circular-chaos.org>
+
+	* m4/gst-args.m4:
+	  Let the AG_GST_ARG_ENABLE_EXPERIMENTAL macro default to disable
+	  building of experimental plugins. Nobody uses it yet and the
+	  --enable--experimental stuff from gst-plugins-good defaults to
+	  disable too.
+
+2007-09-06  Tim-Philipp Müller  <tim at centricular dot net>
+
+	* gtk-doc-plugins.mak:
+	  Just use the normal 'check' target and avoid a circular
+	  dependency.
+
+2007-09-06  Tim-Philipp Müller  <tim at centricular dot net>
+
+	* gtk-doc-plugins.mak:
+	  Add rule to error out if .hierarchy file contains tabs.
+
+2007-08-20  Tim-Philipp Müller  <tim at centricular dot net>
+
+	* download-translations:
+	* po.mak:
+	  If there are new languages, they need to be added to po/LINGUAS.
+
+2007-08-20  Tim-Philipp Müller  <tim at centricular dot net>
+
+	* download-translations:
+	* po.mak:
+	  Fix up 'download-po' a bit, so that we find new translations
+	  for languages that aren't in our po/LINGUAS file yet too.
+
+2007-07-16  Jan Schmidt  <thaytan@mad.scientist.com>
+
+	* gst.supp:
+	Add a suppression for GLib caching the tmp dir seen on an
+	Ubuntu Feisty system.
+
+2007-07-13  Jan Schmidt  <thaytan@mad.scientist.com>
+
+	* m4/gst-feature.m4:
+	If we want to use 'echo -e', call /bin/echo instead of the shell's
+	since -e is a bash extension, and our /bin/sh might not be being
+	provided by bash.
+
+2007-07-01  Thomas Vander Stichele  <thomas at apestaart dot org>
+
+	* po.mak:
+	  Translation project has moved.  Also, no idea how this used to
+	  work given that we weren't downloading a .po file.
+
+2007-06-25  Stefan Kost  <ensonic@users.sf.net>
+
+	* gst-xmlinspect.py:
+	* plugins.xsl:
+	  Also extract element caps for plugin-docs. Fixes parts of #117692.
+
+2007-06-21  Tim-Philipp Müller  <tim at centricular dot net>
+
+	Patch by: Andreas Schwab
+
+	* m4/gst-feature.m4:
+	  Fix quoting (#449493).
+
+2007-06-10  Sebastian Dröge  <slomo@circular-chaos.org>
+
+	* m4/gst-parser.m4:
+	Only generate the parser if bison >= 1.875 _and_ flex >= 2.5.31 is
+	installed and use pre-generated sources otherwise. Fixes bug #444820.
+
+2007-05-11  Michael Smith <msmith@fluendo.com>
+
+	* gst.supp:
+	  Suppression variant for our good friend the TLS leak, this time for
+	  Ubuntu Feisty/x86.
+
+2007-05-09  Tim-Philipp Müller  <tim at centricular dot net>
+
+	* gtk-doc-plugins.mak:
+	  Fix make distcheck again; change some spaces to tabs in makefile.
+
+2007-04-29  Thomas Vander Stichele  <thomas at apestaart dot org>
+
+	* gtk-doc-plugins.mak (-module):
+	  Error out when the html build step gives warnings, so they get
+	  fixed properly.
+
+2007-04-23  Stefan Kost  <ensonic@users.sf.net>
+
+	* m4/gst-feature.m4:
+	  Add macro AG_GST_PARSE_SUBSYSTEM_DISABLES that checks the defines in
+	  the configuration header and AC_DEFINES the setings.
+
+2007-04-19  Sebastian Dröge  <slomo@circular-chaos.org>
+
+	Patch by: Vincent Torri <vtorri at univ-evry dot fr>
+
+	* m4/gst-parser.m4:
+	Put the AC_MSG_RESULT output in brackets to get it properly written to
+	the terminal.
+
+2007-04-18  Sebastian Dröge  <slomo@circular-chaos.org>
+
+	* m4/gst-parser.m4:
+	Check for flex >= 2.5.31 and set GENERATE_PARSER if we have at least
+	that version. Otherwise use pre-generated parser sources as we can't
+	raise the required flex version. HAVE_MT_SAVE_FLEX is obsolete now
+	as we use a new enough flex version anyway. First part of #349180
+
+2007-04-10  Thomas Vander Stichele  <thomas at apestaart dot org>
+
+	* m4/gst-check.m4:
+	  Allow pre-setting the GST(PB)_TOOLS/PLUGINS_DIR variables to help
+	  builds against older GStreamer.
+
+2007-03-25  Sebastian Dröge  <slomo@circular-chaos.org>
+
+	* m4/gst-parser.m4:
+	Fix the flex version check. It ignored the micro version before.
+
+2007-03-09  Jan Schmidt  <thaytan@mad.scientist.com>
+
+	* check.mak:
+	Use the same timeout when generating valgrind suppressions as 
+	running the valgrind test.
+
+	* gst.supp:
+	Add some more suppressions and stuff.
+
+2007-03-08  Jan Schmidt  <thaytan@mad.scientist.com>
+
+	* check.mak:
+	Make sure GSlice is disabled when building suppressions too.
+
+	* gst.supp:
+	Add around *850* lines of suppressions for one-time initialisations
+	inside libasound and gconf/bonobo/ORBit. I feel so dirty.
+
+2007-03-07  Jan Schmidt  <thaytan@mad.scientist.com>
+
+	* gst.supp:
+	add a suppression for this GConf flup on the FC5 buildbot.
+
+2007-03-06  Jan Schmidt  <thaytan@mad.scientist.com>
+
+	* gst.supp:
+	Make the suppression a little more generic, to catch the FC5 
+	backtrace too.
+
+2007-03-06  Jan Schmidt  <thaytan@mad.scientist.com>
+
+	* gst.supp:
+	Add a suppression for libcdio 0.76. It leaks an internal struct
+	when the CD-ROM device is not accessible.
+
+2007-02-28  Thomas Vander Stichele  <thomas at apestaart dot org>
+
+	* m4/gst-arch.m4:
+	  Move a line that was in the wrong macro
+
+2007-02-28  Thomas Vander Stichele  <thomas at apestaart dot org>
+
+	* m4/gst.m4:
+	  Add
+	* m4/gst-arch.m4:
+	* m4/gst-args.m4:
+	* m4/gst-check.m4:
+	* m4/gst-debuginfo.m4:
+	* m4/gst-default.m4:

+	* m4/gst-libxml2.m4:
+	* m4/gst-parser.m4:
+	* m4/gst-plugin-docs.m4:
+	* m4/gst-plugindir.m4:
+	* m4/gst-valgrind.m4:
+	* m4/gst-x11.m4:
+	  Convert all macros to use AG_GST style so we can properly warn
+	  when they're missing if configure.ac calls AG_GST_INIT
+	  Will require update in all GStreamer modules.
+
+2007-02-11  Stefan Kost  <ensonic@users.sf.net>
+
+	* m4/gst-args.m4:
+	  Remove 'enable' from configure switch description as this leads to 
+	  confusing lines like "disable enable builing ...".
+	* m4/gst-feature.m4:
+	  Fix comment to sound less horrible.
+
+2007-02-07  Tim-Philipp Müller  <tim at centricular dot net>
+
+	Patch by: Will Newton  <will.newton gmail com>
+
+	* m4/gst-check.m4:
+	  Use $PKG_CONFIG rather than pkg-config directly, the one in our path
+	  might not be the one we want, like when cross-compiling. Also, other
+	  macros such as PKG_CHECK_MODULES use $PKG_CONFIG, so we should
+	  probably too just for consistency. Fixes #405288.
+
+2007-01-08  Tim-Philipp Müller  <tim at centricular dot net>
+
+	* m4/gst-parser.m4:
+	  Need to use double square brackets again so m4 doesn't remove them
+	  (fixes #378931).
+
+	* m4/gst-args.m4:
+	  Use double square brackets here as well, for the same reason.
+
+2007-01-05  Tim-Philipp Müller  <tim at centricular dot net>
+
+	* m4/gst-parser.m4:
+	  Use 'sed' rather than 'tr' to strip trailing letters from version
+	  numbers, since 'tr' might not be available and we know sed is
+	  (#378931).
+
+2006-10-21  Tim-Philipp Müller  <tim at centricular dot net>
+
+	* check.mak:
+	  Increase default timeout under valgrind, 60 is just too short and
+	  some tests take a bit longer these days and not everyone has a
+	  beefy machine.
+
+2006-09-29  Michael Smith  <msmith@fluendo.com>
+
+	* gst.supp:
+	  More suppressions for edgy. 
+
+2006-09-28  Jan Schmidt  <thaytan@mad.scientist.com>
+
+	* m4/gst-glib2.m4:
+	Use gmodule-no-export-2.0.pc instead of gmodule-2.0.pc - we neither
+	want nor need --export-dynamic (which ends up making us export a bunch
+	of unneeded symbols)
+
+2006-09-14  Tim-Philipp Müller  <tim at centricular dot net>
+
+	* gst.supp:
+	  Some suppressions for the more recent ld.so in ubuntu edgy.
+
+2006-08-23  Tim-Philipp Müller  <tim at centricular dot net>
+
+	* gst.supp:
+	  Shorten function trail so the suppression works on
+	  my ubuntu dapper system with core cvs as well.
+
+2006-07-28  Jan Schmidt  <thaytan@mad.scientist.com>
+
+	* gst.supp:
+	Extra suppressions from my Ubuntu x86_64 machine
+
+2006-07-24  Tim-Philipp Müller  <tim at centricular dot net>
+
+	Patch by: Frederic Peters <fpeters at entrouvert com>
+
+	* m4/gst-parser.m4:
+	  Need to double square brackets in .m4 files. Should fix bison
+	  version detection with version numbers like 1.23a (#348354).
+
+2006-07-24  Jan Schmidt  <thaytan@mad.scientist.com>
+
+	* check.mak:
+	Valgrind fails to find tests written in tests/check/ directly (rather
+	than a subdir) - because valgrind gets run with a filename that
+	doesn't contain a relative path, it goes searching /usr/bin instead.
+	Run with ./.... to make things work either way.
+
+	* gtk-doc-plugins.mak:
+	Add $(top_builddir)/src as a place to look for plugins
+	when building too, since that's where gst-template keeps things
+
+2006-07-23  Stefan Kost  <ensonic@users.sf.net>
+
+	Patch by: Frederic Peters <fpeters@entrouvert.com>
+
+	* m4/gst-parser.m4:
+	  Fix bison detection (#348354)
+
+2006-07-21  Stefan Kost  <ensonic@users.sf.net>
+
+	* m4/gst-parser.m4:
+	  check for bison and flex
+
+2006-07-13  Thomas Vander Stichele  <thomas at apestaart dot org>
+
+	* m4/gst-plugin-docs.m4:
+	  remove the configure argument for enabling plugin doc build;
+	  having gtk-doc enabled and pyxml present is enough of a trigger
+
+2006-07-03  Thomas Vander Stichele  <thomas at apestaart dot org>
+
+	* coverage/lcov.mak:
+	  fix up rules to work with gst-python as well
+	  run "make lcov" to test and generate the reports
+	  run "make lcov-reset" to redo it after that
+
+2006-07-02  Thomas Vander Stichele  <thomas at apestaart dot org>
+
+	* Makefile.am:
+	* check.mak:
+	  add an inspect target that inspects every element feature,
+	  so we can have that added for coverage
+	* coverage/lcov.mak:
+	  add support for lcov
+
+2006-07-02  Thomas Vander Stichele  <thomas at apestaart dot org>
+
+	* m4/gst-args.m4:
+	  when building with gcov, reset CFLAGS and friends to O0
+
+2006-07-02  Thomas Vander Stichele  <thomas at apestaart dot org>
+
+	* m4/gst-args.m4:
+	  Find the gcov that matches the gcc version
+	  Only allow gcov if we use gcc
+
+2006-07-02  Thomas Vander Stichele  <thomas at apestaart dot org>
+
+	* Makefile.am:
+	* coverage/coverage-report-entry.pl:
+	* coverage/coverage-report.pl:
+	* coverage/coverage-report.xsl:
+	  copy coverage reporting files from dbus
+
+2006-07-01  Thomas Vander Stichele  <thomas at apestaart dot org>
+
+	* m4/gst-args.m4:
+	  libtool strips gcov's -f flags, so libgcov does not get
+	  linked in.  Setting GCOV_LIBS with -lgcov fixes libtool's
+	  stripping
+	  also show what pkg-config-path we set
+
+2006-06-22  Tim-Philipp Müller  <tim at centricular dot net>
+
+	Patch by: Peter Kjellerstedt <pkj at axis com>
+
+	* m4/gst-feature.m4:
+	  Show list of plugins without external dependencies that
+	  will not be built as well (#344136).
+
+2006-06-15  Tim-Philipp Müller  <tim at centricular dot net>
+
+	* m4/gst-plugin-docs.m4:
+	  add GST_PLUGIN_DOCS, which checks for everything needed
+	  to build the plugin docs (namely gtk-doc and pyxml); also
+	  adds a new --enable-plugin-docs configure switch; will
+	  set ENABLE_PLUGIN_DOCS conditional for use in Makefile.am
+	  files (see #344039).
+
+2006-06-11  Thomas Vander Stichele  <thomas at apestaart dot org>
+
+	* m4/gst-check.m4:
+	  add GST_PKG_CHECK_MODULES, which in the normal case of checking
+	  for a dependency lib for a plug-in only needs two arguments
+	  to do the right thing.
+	* m4/gst-feature.m4:
+	  clean up output a little of feature checking; also deal with
+	  non-plug-in feature checks
+	* m4/Makefile.am:
+	* m4/gst-gstreamer.m4:
+	  remove this file; it's a useless check
+
+2006-06-06  Thomas Vander Stichele  <thomas at apestaart dot org>
+
+	* m4/gst-arch.m4:
+	  add PPC64 so we can have separate structure sizes for it
+
+2006-06-05  Edward Hervey  <edward@fluendo.com>
+
+	* gtk-doc.mak:
+	Check for the proper .devhelp2 file to remove.
+
+2006-05-31  Thomas Vander Stichele  <thomas at apestaart dot org>
+
+	* gtk-doc.mak:
+	  allow a magic variable to suppress errors from docbuilding
+
+2006-05-30  Thomas Vander Stichele  <thomas (at) apestaart (dot) org>
+
+	* gtk-doc.mak:
+	  error out if gtkdoc-mktmpl finds unused declarations
+
+2006-05-28  Edward Hervey  <edward@fluendo.com>
+
+	* gst.supp:
+	Reverting previous commit.  That's good to know, Edward, but why ?
+	
+2006-05-28  Edward Hervey  <edward@fluendo.com>
+
+	* gst.supp:
+	Added suppresion for memleak in g_option_context_parse on fc5-64
+
+2006-05-19  Thomas Vander Stichele  <thomas at apestaart dot org>
+
+	* m4/gst-check.m4:
+	  set GSTPB_PLUGINS_DIR just like GST_PLUGINS_DIR
+
+2006-05-18  Tim-Philipp Müller  <tim at centricular dot net>
+
+	* check.mak:
+	  Fix 'make help' in check directories, it should be
+	  'valgrind.gen-suppressions' not 'valgrind-gen-suppressions'
+	  (not changing target to match help string on purpose to keep
+	  scripts etc. functional).
+
+2006-05-18  Thomas Vander Stichele  <thomas at apestaart dot org>
+
+	Patch by: Peter Kjellerstedt
+
+	* m4/gst-arch.m4:
+	  add support for CRIS and CRISv32.
+
+2006-05-17  Jan Schmidt  <thaytan@mad.scientist.com>
+
+	* m4/gst-args.m4:
+	Fix the macros for command-line supplied package and origin names
+	so they don't end up being configure as "" (Fixes #341479)
+
+2006-05-14  Jan Schmidt <thaytan@mad.scientist.com>
+
+	* gtk-doc.mak:
+	Add uninstall rule to remove .devhelp2 files.
+
+2006-05-09  Edward Hervey  <edward@fluendo.com>
+
+	* gst.supp: 
+	  Add suppression for GSlice version of
+	  g_type_init calloc leak
+
+2006-04-05  Michael Smith  <msmith@fluendo.com>
+
+	* gst.supp:
+	  Delete a bogus suppression for the registry code.
+	  Generalise a suppression for a glib bug (see #337404)
+
+2006-04-04  Michael Smith <msmith@fluendo.com>
+
+	* gst.supp:
+	  Add a leak suppression: the existing glibc-doesn't-free-TLS one
+	  wasn't triggering here.
+
+2006-04-04  Michael Smith <msmith@fluendo.com>
+
+	* gst.supp:
+	  Add some minimally-neccesary suppressions for my x86/dapper system.
+
+2006-04-01  Thomas Vander Stichele  <thomas at apestaart dot org>
+
+	* plugins.xsl:
+	  Do not display an origin link if origin does not start with http
+	  See #323798
+

+2006-03-08  Jan Schmidt  <thaytan@mad.scientist.com>
+
+	* check.mak:

+2005-10-17  Julien MOUTTE  <julien@moutte.net>
+
+	* m4/gst-check.m4: I know Thomas will kill me but this

+
+2005-10-11  Thomas Vander Stichele  <thomas at apestaart dot org>
+

+
+2005-10-11  Edward Hervey  <edward@fluendo.com>
+
+	* gst.supp: 
+	made the <g_type_init calloc 2> suppression more generic
+	Added pthread memleak suppresions
+	Added nss_parse_* memleak suppresion (used by g_option_context_parse)
+
+2005-10-11  Thomas Vander Stichele  <thomas at apestaart dot org>
+

+
+	* Makefile.am:

+	  Make the scanobj code reflect registry/plugin API changes
+
+2005-09-15  Thomas Vander Stichele  <thomas at apestaart dot org>
+
+	* gtk-doc-plugins.mak:
+	  split out scanobj step (which will be run by doc maintainer)
+	  from scan step (which will be run on every build)
+	  clean up some of the commands for make distcheck
+
+2005-09-15  Thomas Vander Stichele  <thomas at apestaart dot org>
+
+	* gtk-doc-plugins.mak:
+	* mangle-tmpl.py:
+	  first stab at reorganizing the plugins build so we can maintain

+
+2005-09-14  David Schleef  <ds@schleef.org>
+
+	* as-libtool.mak: Remove
+	* m4/as-libtool.m4: The libtool bug that this worked around has
+	  been fixed.
+	* m4/as-version.m4: Don't define GST_RELEASE, since it causes
+	  config.h to be regenerated needlessly, and we don't use it.
+
+2005-09-14  Thomas Vander Stichele  <thomas at apestaart dot org>
+
+	* gtk-doc-plugins.mak:
+	  error out on inspect failure
+
+2005-09-14  Michael Smith <msmith@fluendo.com>
+
+	* glib-gen.mak:
+	  Don't call glib-mkenums with arguments that confuse/break MinGW,
+	  fixes 316155.
+
+2005-09-03  Thomas Vander Stichele  <thomas at apestaart dot org>
+
+	* gtk-doc-plugins.mak:
+	* gtk-doc.mak:
+	* m4/gst-doc.m4:
+	  separate out gtk-doc and docbook stuff
+	  have two separate --enable configure flags
+
+2005-08-26  Thomas Vander Stichele  <thomas at apestaart dot org>
+
+	* check.mak:
+	  add a .gdb target; rebuild registry for each target, otherwise
+	  a code rebuild always triggers a reg rebuild, and it's just too
+	  annoying
+	* gstdoc-scangobj:
+
+2005-08-21  Thomas Vander Stichele  <thomas at apestaart dot org>
+
+	* check.mak:
+	  separate out REGISTRY_ENVIRONMENT; we want to use that from
+	  our valgrind runs, but we also want TESTS_ENVIRONMENT to contain
+	  everything that the first test, gst-register, needs
+
+2005-08-21  Thomas Vander Stichele  <thomas at apestaart dot org>
+
+	* check.mak:
+	  parse output of valgrind and check for definitely lost, and error
+	  out; somehow I was led to believe valgrind returns non-zero for
+	  leaks, but I can't make it do that, so let's parse
+
+2005-08-20  Thomas Vander Stichele  <thomas at apestaart dot org>
+
+	* check.mak:
+	  for some weird reason valgrind does not report actual memleaks
+	  if GST_PLUGIN_PATH is set to anything but the core gstreamer dir
+	  while valgrind is running.  Since the registry is going to go
+	  anyway, I don't want to waste any more time on this; I just run
+	  valgrind without GST_PLUGIN_PATH set.  Since the registry loading
+	  doesn't check if GST_PLUGIN_PATH got changed as a reason to rebuild
+	  the registry, that's actually fine.
+
+2005-08-15  Thomas Vander Stichele  <thomas at apestaart dot org>
+
+	* mangle-tmpl.py:
+	  keep original Long_Description; only insert an include if it's
+	  not already the first line in there
+	* plugins.xsl:
+	  output more information for plugins, including an origin hyperlink
+
+2005-08-15  Thomas Vander Stichele  <thomas at apestaart dot org>
+
+	* gst-xmlinspect.py:
+	  a first stab at inspecting plugins and outputting an xml description
+	* gtk-doc-plugins.mak:
+	  a gtk-doc using snippet for plugins documentation
+	* plugins.xsl:
+	  a stylesheet to convert gst-xmlinspect.py output to docbook output

+#
+# SYNOPSIS
+#
+#   AX_CREATE_STDINT_H [( HEADER-TO-GENERATE [, HEDERS-TO-CHECK])]
+#
+# DESCRIPTION
+#
+#   the "ISO C9X: 7.18 Integer types <stdint.h>" section requires the
+#   existence of an include file <stdint.h> that defines a set of
+#   typedefs, especially uint8_t,int32_t,uintptr_t. Many older
+#   installations will not provide this file, but some will have the
+#   very same definitions in <inttypes.h>. In other enviroments we can
+#   use the inet-types in <sys/types.h> which would define the typedefs
+#   int8_t and u_int8_t respectivly.
+#
+#   This macros will create a local "_stdint.h" or the headerfile given
+#   as an argument. In many cases that file will just "#include
+#   <stdint.h>" or "#include <inttypes.h>", while in other environments
+#   it will provide the set of basic 'stdint's definitions/typedefs:
+#
+#     int8_t,uint8_t,int16_t,uint16_t,int32_t,uint32_t,intptr_t,uintptr_t
+#     int_least32_t.. int_fast32_t.. intmax_t
+#
+#   which may or may not rely on the definitions of other files, or
+#   using the AC_CHECK_SIZEOF macro to determine the actual sizeof each
+#   type.
+#
+#   if your header files require the stdint-types you will want to
+#   create an installable file mylib-int.h that all your other
+#   installable header may include. So if you have a library package
+#   named "mylib", just use
+#
+#        AX_CREATE_STDINT_H(mylib-int.h)
+#
+#   in configure.ac and go to install that very header file in
+#   Makefile.am along with the other headers (mylib.h) - and the
+#   mylib-specific headers can simply use "#include <mylib-int.h>" to
+#   obtain the stdint-types.
+#
+#   Remember, if the system already had a valid <stdint.h>, the
+#   generated file will include it directly. No need for fuzzy
+#   HAVE_STDINT_H things... (oops, GCC 4.2.x has deliberatly disabled
+#   its stdint.h for non-c99 compilation and the c99-mode is not the
+#   default. Therefore this macro will not use the compiler's stdint.h
+#   - please complain to the GCC developers).

+
+dnl Macro to add for using GNU gettext.
+
+dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
+dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
+dnl    default (if it is not specified or empty) is 'no-libtool'.
+dnl    INTLSYMBOL should be 'external' for packages with no intl directory,
+dnl    and 'no-libtool' or 'use-libtool' for packages with an intl directory.
+dnl    If INTLSYMBOL is 'use-libtool', then a libtool library
+dnl    $(top_builddir)/intl/libintl.la will be created (shared and/or static,
+dnl    depending on --{enable,disable}-{shared,static} and on the presence of
+dnl    AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
+dnl    $(top_builddir)/intl/libintl.a will be created.
+dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
+dnl    implementations (in libc or libintl) without the ngettext() function
+dnl    will be ignored.  If NEEDSYMBOL is specified and is
+dnl    'need-formatstring-macros', then GNU gettext implementations that don't
+dnl    support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
+dnl INTLDIR is used to find the intl libraries.  If empty,
+dnl    the value `$(top_builddir)/intl/' is used.
+dnl
+dnl The result of the configuration is one of three cases:
+dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
+dnl    and used.
+dnl    Catalog format: GNU --> install in $(datadir)
+dnl    Catalog extension: .mo after installation, .gmo in source tree
+dnl 2) GNU gettext has been found in the system's C library.
+dnl    Catalog format: GNU --> install in $(datadir)
+dnl    Catalog extension: .mo after installation, .gmo in source tree
+dnl 3) No internationalization, always use English msgid.
+dnl    Catalog format: none
+dnl    Catalog extension: none
+dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
+dnl The use of .gmo is historical (it was needed to avoid overwriting the
+dnl GNU format catalogs when building on a platform with an X/Open gettext),
+dnl but we keep it in order not to force irrelevant filename changes on the
+dnl maintainers.

+dnl                   DISABLE-BY-DEFAULT, ACTION-IF-USE, ACTION-IF-NOTUSE)
+dnl
+dnl This macro adds a command line argument to allow the user to enable
+dnl or disable a feature, and if the feature is enabled, performs a supplied
+dnl test to check if the feature is available.
+dnl
+dnl The test should define HAVE_<FEATURE-NAME> to "yes" or "no" depending
+dnl on whether the feature is available.
+dnl
+dnl The macro will set USE_<FEATURE-NAME> to "yes" or "no" depending on
+dnl whether the feature is to be used.
+dnl Thomas changed this, so that when USE_<FEATURE-NAME> was already set
+dnl to no, then it stays that way.
+dnl
+dnl The macro will call AM_CONDITIONAL(USE_<FEATURE-NAME>, ...) to allow
+dnl the feature to control what is built in Makefile.ams.  If you want
+dnl additional actions resulting from the test, you can add them with the
+dnl ACTION-IF-USE and ACTION-IF-NOTUSE parameters.
+dnl
+dnl FEATURE-NAME        is the name of the feature, and should be in
+dnl                     purely upper case characters.
+dnl FEATURE-DESCRIPTION is used to describe the feature in help text for
+dnl                     the command line argument.
+dnl DEPENDENT-PLUGINS   lists any plug-ins which depend on this feature.
+dnl TEST-FOR-FEATURE    is a test which sets HAVE_<FEATURE-NAME> to "yes"
+dnl                     or "no" depending on whether the feature is
+dnl                     available.
+dnl DISABLE-BY-DEFAULT  if "disabled", the feature is disabled by default,
+dnl                     if any other value, the feature is enabled by default.
+dnl ACTION-IF-USE       any extra actions to perform if the feature is to be
+dnl                     used.
+dnl ACTION-IF-NOTUSE    any extra actions to perform if the feature is not to
+dnl                     be used.
