* Original Author:

* 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.
* -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>
