%description
The RPM Package Manager (RPM) is a powerful command line driven
package management system capable of installing, uninstalling,
verifying, querying, and updating software packages.  Each software
package consists of an archive of files along with information about
the package like its version, a description, etc.

%package devel
Summary: Development files for applications which will manipulate RPM packages.
Group: Development/Libraries
Requires: rpm = %{rpm_version}, popt = 1.7

%description devel
This package contains the RPM C library and header files.  These
development files will simplify the process of writing programs which
manipulate RPM packages and databases. These files are intended to
simplify the process of creating graphical package managers or any
other tools that need an intimate knowledge of RPM packages in order
to function.

This package should be installed if you want to develop programs that
will manipulate RPM packages and databases.

%package build
Summary: Scripts and executable programs used to build packages.
Group: Development/Tools
Requires: rpm = %{rpm_version}

%description build
This package contains scripts and executable programs that are used to
build packages using RPM.

%if %{with_python_subpackage}
%package python
Summary: Python bindings for apps which will manipulate RPM packages.
Group: Development/Libraries
Requires: rpm = %{rpm_version}
Requires: python >= 1.5.2
Requires: popt = 1.7

%description python
The rpm-python package contains a module which permits applications
written in the Python programming language to use the interface
supplied by RPM (RPM Package Manager) libraries.

This package should be installed if you want to develop Python
programs that will manipulate RPM packages and databases.
%endif

%if %{with_perl_subpackage}
%package perl
Summary: Native bindings to the RPM API for Perl.
Group: Development/Languages
URL: http://www.cpan.org
Provides: perl(RPM::Database) = %{rpm_version}

Requires: rpm = %{rpm_version}
Requires: perl >= 0:5.00503
Requires: popt = 1.7
Obsoletes: perl-Perl-RPM

%description perl
The Perl-RPM module is an attempt to provide Perl-level access to the
complete application programming interface that is a part of the Red
Hat Package Manager (RPM). Rather than have scripts rely on executing
RPM commands and parse the resulting output, this module aims to give
Perl programmers the ability to do anything that would otherwise have
been done in C or C++.

The interface is being designed and laid out as a collection of
classes, at least some of which are also available as tied-hash
implementations.

At this time, the interface only provides access to the database of
installed packages, and header data retrieval for RPM and SRPM files
is not yet installed.  Error management and the export of most defined
constants, through RPM::Error and RPM::Constants, respectively, are
also available.

%endif

%package -n popt
Summary: A C library for parsing command line parameters.
Group: Development/Libraries
Version: 1.7

%description -n popt
Popt is a C library for parsing command line parameters.  Popt was
heavily influenced by the getopt() and getopt_long() functions, but it
improves on them by allowing more powerful argument expansion.  Popt
can parse arbitrary argv[] style arrays and automatically set
variables based on command line arguments.  Popt allows command line
arguments to be aliased via configuration files and includes utility
functions for parsing arbitrary strings into argv[] arrays using
shell-like rules.

Install popt if you're a C programmer and you'd like to use its
capabilities.

%changelog
* Mon Sep 24 2001 Jeff Johnson <jbj@redhat.com>
- Start rpm-4.1.
- loosely wire beecrypt library into rpm.
- drop rpmio/base64.[ch] in favor of beecrypt versions.
- drop lib/md5*.[ch] files in favor of beecrypt.
- legacy: drop brokenMD5 support (rpm-2.3.3 to rpm-2.3.8 on sparc).
- eliminate DYING code.
- bind beecrypt md5/sha1 underneath rpmio.
- create RFC-2440 OpenPGP API in rpmio.
- proof-of-concept GPG/DSA verification for legacy signatures.
- upgrade to beecrypt-2.2.0pre.
- proof-of-concept PGP/RSA verification for legacy signatures.
- ratchet up to lclint "strict" level.
- upgrade to db-4.0.7.
- use only header methods, routines are now static.
- beecrypt is at least as good as pgp/gpg on verify, pulling the plug.
- add :base64 and :armor format extensions, dump binary tags in hex.
- proof-of-concept pubkey retrieval from RPM-{PGP,GPG}-KEY.
- stupid macros to configure public key file paths.
- all symbols but hdrVec are now forward references in linkage.
- generate an rpm header on the fly for imported pubkeys.
- wire transactions through rpmcli signature modes.
- wire transactions through rpmcli query/verify modes.
- wire transactions through rpmcli install/erase modes.
- legacy signatures always checked where possible on package read.
- wire transactions through rpmcli build modes.
- lazy rpmdb open/close through transaction methods (mostly anyways).
- no-brainer refcounts for rpmdb object.
- check added header against transaction set, replace if newer.
- transaction sets created in cli main.
- no-brainer refcounts for ts object.
- memory indices for dependency check are typedef'd and abstract'd.
- no-brainer refcounts for fi object, debug the mess.
- dump the header early in transaction, recreate fi before installing.
- start hiding availablePackage data/methods in rpmal.c/rpmal.h.
- add some dinky availablePackage methods.
- transaction.c: cleanly uncouple availablePackage from TFI_t.
- add header refcount annotations throughout.
- depends.c: availablePackage is (almost) opaque.
- invent some toy transactionElement iterators.
- create rpmDepSet constructors/destructors.
- create toy rpmDepSet iterators.
