- * Original Author:
- * Todd Brunhoff
- * Tektronix, inc.
- * While a guest engineer at Project Athena, MIT
- *
- * 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.
- * -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>
