+.SH NAME
+imake \- C preprocessor interface to the make utility
+.SH SYNOPSIS
+\fBimake\fP [ \fB\-D\fP\fIdefine\fP ] [ \fB\-I\fP\fIdir\fP ]
+[ \fB\-U\fP\fIdefine\fP ]
+[ \fB\-T\fP\fItemplate\fP ]
+[ \fB\-f\fP \fIfilename\fP ] [ \fB\-C\fP \fIfilename\fP ]
+[ \fB\-s\fP \fIfilename\fP ] [ \fB\-e\fP ]
+[ \fB\-v\fP ]
+.SH DESCRIPTION
+.I Imake
+is used to
+generate \fIMakefiles\fP from a template, a set of \fIcpp\fP macro functions,
+and a per-directory input file called an \fIImakefile\fP. This allows machine
+dependencies (such as compiler options, alternate command names, and special
+\fImake\fP rules) to be kept separate from the descriptions of the
+various items to be built.
+.SH OPTIONS
+The following command line options may be passed to \fIimake\fP:
+.TP 8
+.B \-D\fIdefine\fP
+This option is passed directly to \fIcpp\fP. It is typically used to set
+directory-specific variables. For example, the X Window System uses this
+flag to set \fITOPDIR\fP to the name of the directory containing the top
+of the core distribution and \fICURDIR\fP to the name of the current
+directory, relative to the top.
+.TP 8
+.B \-I\fIdirectory\fP
+This option is passed directly to \fIcpp\fP. It is typically used to
+indicate the directory in which the \fIimake\fP template and configuration
+files may be found.
+.TP 8
+.B \-U\fIdefine\fP
+This option is passed directly to \fIcpp\fP. It is typically used to
+unset variables when debugging \fIimake\fP configuration files.
+.TP 8
+.B \-T\fItemplate\fP
+This option specifies the name of the master template file (which is usually
+located in the directory specified with \fI\-I\fP) used by \fIcpp\fP.
+The default is \fIImake.tmpl\fP.
+.TP 8
+.B \-f \fIfilename\fP
+This option specifies the name of the per-directory input file. The default
+is \fIImakefile\fP.
+.TP 8
+.B \-C \fIfilename\fP
+This option specifies the name of the .c file that is constructed in the
+current directory. The default is \fIImakefile.c\fP.
+.TP 8
+.B \-s \fIfilename\fP
+This option specifies the name of the \fImake\fP description file to be
+generated but \fImake\fP should not be invoked.
+If the \fIfilename\fP is a dash (\-), the
+output is written to \fIstdout\fP. The default is to generate, but
+not execute, a \fIMakefile\fP.
+.TP 8
+.B \-e
+This option indicates the \fIimake\fP should execute the generated
+\fIMakefile\fP. The default is to leave this to the user.
+.TP 8
+.B \-v
+This option indicates that \fIimake\fP should print the \fIcpp\fP command line
+that it is using to generate the \fIMakefile\fP.
+.SH "HOW IT WORKS"
+\fIImake\fP invokes \fIcpp\fP with any \fI\-I\fP or \fI\-D\fP flags passed
+on the command line and passes the name of a file containing the
+following 3 lines:
+.sp
+.nf
+\& #define IMAKE_TEMPLATE "Imake.tmpl"
+\& #define INCLUDE_IMAKEFILE <Imakefile>
+\& #include IMAKE_TEMPLATE
+.fi
+.sp
+where \fIImake.tmpl\fP and \fIImakefile\fP may be overridden by the
+\fI\-T\fP and \fI\-f\fP command options, respectively.
+.PP
+The IMAKE_TEMPLATE typically
+reads in a file containing machine-dependent parameters
+(specified as \fIcpp\fP symbols), a site-specific parameters file,
+a file defining variables,
+a file
+containing \fIcpp\fP macro functions for generating \fImake\fP rules, and
+finally the \fIImakefile\fP (specified by INCLUDE_IMAKEFILE) in the current
+directory. The \fIImakefile\fP uses the macro functions to indicate what
+targets should be built; \fIimake\fP takes care of generating the appropriate
+rules.
+.PP
+.I Imake
+configuration files contain two types of variables, imake variables
+and make variables. The imake variables are interpreted by cpp when
+.I imake
+is run. By convention they are mixed case. The make variables are
+written into the
+.I Makefile
+for later interpretation by
+.I make.
+By convention make variables are upper case.
+.PP
+The rules file (usually named \fIImake.rules\fP in the configuration
+directory) contains a variety of \fIcpp\fP macro functions that are
+configured according to the current platform. \fIImake\fP replaces
+any occurrences of the string ``@@'' with a newline to allow macros that
+generate more than one line of \fImake\fP rules.
+For example, the macro
+.ta 1i 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
+.PP
+\fIImake\fP also replaces any occurrences of the word ``XCOMM'' with
+the character ``#'' to permit placing comments in the Makefile without
+causing ``invalid directive'' errors from the preprocessor.
+.PP
+Some complex \fIimake\fP macros require generated \fImake\fP variables
+local to each invocation of the macro, often because their value
+depends on parameters passed to the macro.
+Such variables can be created by using an \fIimake\fP variable
+of the form \fBXVARdef\fP\fIn\fP, where \fIn\fP is a single digit.
+A unique \fImake\fP variable will be substituted. Later occurrences
+of the variable \fBXVARuse\fP\fIn\fP will
+be replaced by the variable created by the corresponding
+\fBXVARdef\fP\fIn\fP.
+.PP
+On systems whose \fIcpp\fP reduces multiple tabs and spaces to a single
+space, \fIimake\fP attempts to put back any necessary tabs (\fImake\fP is
+very picky about the difference between tabs and spaces). For this reason,
+colons (:) in command lines must be preceded by a backslash (\\).
+.SH "USE WITH THE X WINDOW SYSTEM"
+The X Window System uses \fIimake\fP extensively, for both full builds within
+the source tree and external software. As mentioned above, two special
+variables, \fITOPDIR\fP and \fICURDIR,\fP are set to make referencing files
+using relative path names easier. For example, the following command is
+generated automatically to build the \fIMakefile\fP in the directory
+\fIlib/X/\fP (relative to the top of the sources):
+.sp
+.nf
+ % ../.././config/imake \-I../.././config \\
+ \-DTOPDIR=../../. \-DCURDIR=./lib/X
+.fi
+.sp
+When building X programs outside the source tree, a special symbol
+\fIUseInstalled\fP is defined and \fITOPDIR\fP and
+\fICURDIR\fP are omitted. If the configuration files have been
+properly installed, the script \fIxmkmf\fP(1) may be used.
+.SH "INPUT FILES"
+Here is a summary of the files read by
+.I imake
+as used by X.
+The indentation shows what files include what other files.
+.nf
+.sp
+.ta 3i
+ Imake.tmpl generic variables
+ site.def site-specific, BeforeVendorCF defined
+ *.cf machine-specific
+ *Lib.rules shared library rules
+ site.def site-specific, AfterVendorCF defined
+ Imake.rules rules
+ Project.tmpl X-specific variables
+ *Lib.tmpl shared library variables
+ Imakefile
+ Library.tmpl library rules
+ Server.tmpl server rules
+ Threads.tmpl multi-threaded rules
+.fi
+.LP
+Note that \fIsite.def\fP gets included twice, once before the
+\fI*.cf\fP file and once after. Although most site customizations
+should be specified after the \fI*.cf\fP file, some, such as the
+choice of compiler, need to be specified before, because other
+variable settings may depend on them.
+.LP
+The first time \fIsite.def\fP is included, the variable BeforeVendorCF
+is defined, and the second time, the variable AfterVendorCF is
+defined. All code in \fIsite.def\fP should be inside an #ifdef for
+one of these symbols.

+.SH "ENVIRONMENT VARIABLES"
+The following environment variables may be set, however their use is not
+recommended as they introduce dependencies that are not readily apparent
+when \fIimake\fP is run:
+.TP 5
+.B IMAKEINCLUDE
+If defined, this specifies a ``\-I'' include argument to pass to the
+C preprocessor. E.g., ``\-I/usr/X11/config''.
+.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 cc -E or __cpp__, depending on the OS specific configuration.
+.TP 5
+.B IMAKEMAKE
+If defined, this should be a valid path to a make program,
+such as ``/usr/local/make''.
+By default,
+.I imake
+will use whatever
+.I make
+program is found using
+.I execvp(3).
+This variable is only used if the ``\-e'' option is specified.
