-.SH DESCRIPTION
-.I Imake
-takes a template and an Imakefile and runs the C preprocessor on it producing a
-temporary makefile in /usr/tmp. It then runs
-.I make
-on this pre-processed makefile.
-See IMPLEMENTATION DETAIL below.
-.PP
-By default,
-.I Imake
-looks first for the file named
-.I Imakefile
-and if that fails, looks for the file named
-.I imakefile,
-both in the current working directory.
-.SH OPTIONS
-.TP 5
-.B \-Ddefine
-Define.
-This argument is passed on to the preprocessor, cpp.
-This can also be accomplished with the environment variable,
-IMAKEINCLUDE.
-.TP 5
-.B \-Idirectory
-Include directory.
-This argument is passed on to the preprocessor, cpp.
-This can also be accomplished with the environment variable,
-IMAKEINCLUDE.
-.TP 5
-.B \-T template
-Template file.
-Specifies the template file to be initially included by cpp,
-instead of the default file
-.I Imake.template.
-.TP 5
-.B \-f imakefile
-File.
-Specifies an alternate imakefile for
-.I imake to use.
-.TP 5
-.B \-s [ filename ]
-Show.
-.I Imake
-will preprocess the imakefile,
-and direct it to the standard output.
-The
-.I make
-program will not be invoked.
-If the filename argument is present
-the output will be directed instead to the named file.
-Typically, this is
-.I \-s Makefile.
-.TP 5
-.B \-v
-Verbose.
-.I Imake
-will display the command line it uses to invoke the C preprocessor before
-actually doing so.
-.SH "ENVIRONMENT VARIABLES"
-Imake consults its environment for three variables:
-.TP 5
-.B IMAKEINCLUDE
-If defined, this should be a valid include argument for the
-C preprocessor. E.g. ``-I/usr/include/local''.
-Actually, any valid
-.I cpp
-argument will work here.
-.TP 5
-.B IMAKECPP
-If defined, this should be a valid path to a preprocessor program.
-E.g. ``/usr/local/cpp''.
-By default,
-.I imake
-will use /lib/cpp.
-.TP 5
-.B IMAKEMAKE
-If defined, this should be a valid path to a make program.
-E.g. ``/usr/local/make''.
-By default,
-.I imake
-will use whatever
-.I make
-program is found using
-.I execvp(3).
-.SH IMPLEMENTATION DETAIL
-.I Imake
-first determins the name of the imakefile from the command line \-f
-flag or from the content of the current directory, depending
-on whether Imakefile or imakefile exist.
-We shall call this \fI<imakefile>\fP.
-It also determines the name of the template
-from the command line \-T flag or the default, Imake.template.
-Call this \fI<template>\fP.
-.PP
-The program then examines the imakefile looking for any lines
-that begin with a '#' character. If it finds one,
-it checks to see if it is a valid C preprocessor directive
-from the set
-.I #include,
-.I #define,
-.I #undef,
-.I #ifdef,
-.I #else,
-.I #endif
-or
-.I #if.
-If it is,
-.I imake
-leaves it unchanged.
-If not,
-it pads the beginning of the line with a null C comment ``/**/''
-so that the line will by untouched by the preprocessor.
-This is usefull for preserving the use of
-.I make
-style ``#'' comments.
-If any lines needed to be changed,
-a temporary file named /tmp/tmp-imake.* will receive the "padded"
-imakefile.
-Call this file, whether it needed to be changed or not,
-\fI<input-imakefile>\fP.
-.PP
-Then the program
-starts up the C preprocessor with the command line
-.RS 5
-.sp 1
-/lib/cpp -I. -I/usr/lib/local/imake.includes -Uunix
-.sp 1
-.RE
-perhaps prepending the argument list with the IMAKEINCLUDE
-environment variable,
-the \fI\-I\fP, and the \fI\-D\fP command line arguments;
-or changing the preprocessor program to the IMAKECPP environment variable.
-Standard input is from the
-.I imake
-program and standard output is directed to a temporary file in
-/usr/tmp/tmp-make.*;
-unless there was an argument to the \-s flag, in which case
-output is directed there.
-Call this file \fI<makefile>\fP.
-The first three lines provided as input to the preprocessor
-will be
-.RS 5
-.sp 1
-#define IMAKE_TEMPLATE "\fI<template>\fP"
-.br
-#define INCLUDE_IMAKEFILE "\fI<input-imakefile>\fP"
-.br
-#include IMAKE_TEMPLATE
-.sp 1
-.RE
-.PP
-Note that this implies that the template must have, at a bare minimum,
-the line
-.RS 5
-.sp 1
-#include INCLUDE_IMAKEFILE
-.sp 1
-.RE
-.PP
-Next,
-.I imake
-reads the entire output of the preprocessor into memory,
-stripping off any double '@' signs encountered in the input.
-This is very useful for writing cpp multi-line macros that
-won't be coalesced into a single line the way
-.I cpp
-normally does.
-In addition, trailing white space on any line is thrown away to keep
-.I make
-from getting upset;
-and most blank lines are thrown
-away.
-For example, the macro
-.ta .8i 1.6i 5i
-.nf
-
-#define program_target(program, objlist) @@\e
-program: objlist @@\e
- $(CC) -o $@ objlist $(LDFLAGS)
-
-.fi
-when called with
-.I "program_target(foo, foo1.o foo2.o)"
-will expand to
-.nf
-
-foo: foo1.o foo2.o
- $(CC) -o $@ foo1.o foo2.o $(LDFLAGS)
-
-.fi
-.DT
-.PP
-Finally,
-if the
-.B -s
-option has not been specified,
-.I imake
-calls the program
-.RS 5
-.sp 1
- make MAKE=\fI<program>\fP MAKEFILE=\fI<imakefile>\fP -f \fI<makefile>\fP makeargs
-.sp 1
-.RE
-where ``makeargs'' is replaced with any arguments found on the command line.

-.SH "BUGS"
-The C-preprocessor, Cpp,
-on a Sun compresses all tabs in a macro expansion to a single
-space. It also replaces an escaped newline with a space instead of
-deleting it. There is a kludge in the code to try to get around this
-but it depends on the fact that all targets have a ':' somewhere in
-the line and all actions for a target do not have a ':'.
-.PP
-You can use \fImake\fP-style '#' comments in the Imakefile, but
-not in the template or any other included files. If you want
-them, you must preceed them with a C null comment, /**/.

- *
- * imake: the include-make program.
- *
- * Usage: imake [-Idir] [-Ddefine] [-T] [-f imakefile ] [-s] [-e] [-v] [make flags]
- *
- * Imake takes a template makefile (Imake.tmpl) and runs cpp on it
- * producing a temporary makefile in /tmp. It then runs make on
- * this pre-processed 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
- * -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.
- *
- * 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. Start up cpp an provide it with three lines of input:
- * #define IMAKE_TEMPLATE " <template> "
- * #define INCLUDE_IMAKEFILE < <imakefile> >
- * #include IMAKE_TEMPLATE
- * 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
- * 4. Gather the output from cpp, and clean it up, expanding @@ to
- * newlines, stripping trailing white space, cpp control lines,
- * and extra blank lines. This cleaned output is placed in a
- * temporary file. Call this <makefile>.
- * 5. Start up make specifying <makefile> as its input.
- *
- * 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>
