+ *
+ * imake: the include-make program.
+ *
+ * Usage: imake [-Idir] [-Ddefine] [-T template] [-f imakefile ] [-C Imakefile.c ] [-s] [-e] [-v] [make flags]
+ *
+ * Imake takes a template file (Imake.tmpl) and a prototype (Imakefile)
+ * and runs cpp on them producing a Makefile. It then optionally runs make
+ * on the Makefile.
+ * Options:
+ * -D define. Same as cpp -D argument.
+ * -U undefine. Same as cpp -U argument.
+ * -W warning. Same as cpp -W argument.
+ * -I Include directory. Same as cpp -I argument.
+ * -T template. Designate a template other
+ * than Imake.tmpl
+ * -f specify the Imakefile file
+ * -C specify the name to use instead of Imakefile.c
+ * -s[F] show. Show the produced makefile on the standard
+ * output. Make is not run is this case. If a file
+ * argument is provided, the output is placed there.
+ * -e[F] execute instead of show; optionally name Makefile F
+ * -v verbose. Show the make command line executed.
+ *
+ * Environment variables:
+ *
+ * IMAKEINCLUDE Include directory to use in addition to "."
+ * IMAKECPP Cpp to use instead of /lib/cpp
+ * IMAKEMAKE make program to use other than what is
+ * found by searching the $PATH variable.
+ * Other features:
+ * imake reads the entire cpp output into memory and then scans it
+ * for occurences of "@@". If it encounters them, it replaces it with
+ * a newline. It also trims any trailing white space on output lines
+ * (because make gets upset at them). This helps when cpp expands
+ * multi-line macros but you want them to appear on multiple lines.
+ * It also changes occurences of "XCOMM" to "#", to avoid problems
+ * with treating commands as invalid preprocessor commands.
+ *
+ * The macros MAKEFILE and MAKE are provided as macros
+ * to make. MAKEFILE is set to imake's makefile (not the constructed,
+ * preprocessed one) and MAKE is set to argv[0], i.e. the name of
+ * the imake program.
+ *
+ * Theory of operation:
+ * 1. Determine the name of the imakefile from the command line (-f)
+ * or from the content of the current directory (Imakefile or imakefile).
+ * Call this <imakefile>. This gets added to the arguments for
+ * make as MAKEFILE=<imakefile>.
+ * 2. Determine the name of the template from the command line (-T)
+ * or the default, Imake.tmpl. Call this <template>
+ * 3. Determine the name of the imakeCfile from the command line (-C)
+ * or the default, Imakefile.c. Call this <imakeCfile>
+ * 4. Store lines of input into <imakeCfile>:
+ * - A c-style comment header (see ImakefileCHeader below), used
+ * to recognize temporary files generated by imake.
+ * - If DEFAULT_OS_NAME is defined, format the utsname struct and
+ * call the result <defaultOsName>. Add:
+ * #define DefaultOSName <defaultOsName>
+ * - If DEFAULT_OS_MAJOR_REV is defined, format the utsname struct
+ * and call the result <defaultOsMajorVersion>. Add:
+ * #define DefaultOSMajorVersion <defaultOsMajorVersion>
+ * - If DEFAULT_OS_MINOR_REV is defined, format the utsname struct
+ * and call the result <defaultOsMinorVersion>. Add:
+ * #define DefaultOSMinorVersion <defaultOsMinorVersion>
+ * - If DEFAULT_OS_TEENY_REV is defined, format the utsname struct
+ * and call the result <defaultOsTeenyVersion>. Add:
+ * #define DefaultOSTeenyVersion <defaultOsTeenyVersion>
+ * - If DEFAULT_MACHINE_ARCITECTURE is defined, format the utsname struct
+ * and define the corresponding macro. (For example on the amiga,
+ * this will define amiga in addition to m68k).
+ * - If the file "localdefines" is readable in the current
+ * directory, print a warning message to stderr and add:
+ * #define IMAKE_LOCAL_DEFINES "localdefines"
+ * #include IMAKE_LOCAL_DEFINES
+ * - If the file "admindefines" is readable in the current
+ * directory, print a warning message to stderr and add:
+ * #define IMAKE_ADMIN_DEFINES "admindefines"
+ * #include IMAKE_ADMIN_DEFINES
+ * - The following lines:
+ * #define INCLUDE_IMAKEFILE < <imakefile> >
+ * #define IMAKE_TEMPLATE " <template> "
+ * #include IMAKE_TEMPLATE
+ * - If the file "adminmacros" is readable in the current
+ * directory, print a warning message to stderr and add:
+ * #define IMAKE_ADMIN_MACROS "adminmacros"
+ * #include IMAKE_ADMIN_MACROS
+ * - If the file "localmacros" is readable in the current
+ * directory, print a warning message to stderr and add:
+ * #define IMAKE_LOCAL_MACROS "localmacros"
+ * #include IMAKE_LOCAL_MACROS
+ * 5. Start up cpp and provide it with this file.
+ * Note that the define for INCLUDE_IMAKEFILE is intended for
+ * use in the template file. This implies that the imake is
+ * useless unless the template file contains at least the line
+ * #include INCLUDE_IMAKEFILE
+ * 6. Gather the output from cpp, and clean it up, expanding @@ to
+ * newlines, stripping trailing white space, cpp control lines,
+ * and extra blank lines, and changing XCOMM to #. This cleaned
+ * output is placed in a new file, default "Makefile", but can
+ * be specified with -s or -e options.
+ * 7. Optionally start up make on the resulting file.
+ *
+ * The design of the template makefile should therefore be:
+ * <set global macros like CFLAGS, etc.>
+ * <include machine dependent additions>
+ * #include INCLUDE_IMAKEFILE
+ * <add any global targets like 'clean' and long dependencies>
