           FvwmM4 - the FVWM  M4 pre-processor

## SYNOPSIS

           FvwmM4  is  spawned by fvwm, so no command line invocation
           will work.

## DESCRIPTION

           When called, this module will attempt to have M4  pre-pro-
           cess  the  file specified in its invocation, and then have
           fvwm read the resulting file.

## INVOCATION

           FvwmM4 can be invoked by inserting the  line  'FvwmM4'  in
           the  .fvwmrc  file.  It  can also be called from a menu or
           mouse binding.  If the user wants his entire .fvwmrc  file
           pre-processed  with FvwmM4, then fvwm should be invoked as
           fvwm -f "FvwmM4 .fvwmrc". Note that the  argument  to  the
           option  "-f"  should  be  enclosed in quotes, and no other
           quoting should be used. For example, a typical  invocation
           might be

                fvwm -f "FvwmM4 -m4-squote { -m4-equote } .fvwmrc"

           Some options can be specified on the command line:

           -m4-prefix
                  I  think  this  makes all the m4 directives require
                  the prefix "m4_".

           -m4opt Lets you pass an option to the m4 program.

           -m4-squote
                  Lets you change the m4 start-of-quote character  to
                  character.

           -m4-equote
                  Lets  you  change  the m4 end-of-quote character to
                  character.

           -m4prog
                  Instead of invoking "m4", fvwm will invoke name.

           -debug Causes the  temporary  file  create  by  m4  to  be
                  retained.  This file is usually called "/tmp/fvwmr-
                  cXXXXXX"

           FvwmM4 defines some values for use  in  the  pre-processor
           file:

           TWM_TYPE
                  Always set to "fvwm".

           SERVERHOST
                  The name of the machine running the X Server.

           CLIENTHOST
                  The name of the machine running fvwm.

           HOSTNAME
                  The hostname of the machine running fvwm. Generally
                  the same as CLIENTHOST.

           OSTYPE The operating system for CLIENTHOST.

           USER   The name of the person running fvwm.

           VERSION
                  The X11 version.

           REVISION
                  The X11 revision number.

           VENDOR The X server vendor.

           RELEASE
                  The X server release number.

           WIDTH  The screen width in pixels.

           HEIGHT The screen height in pixels.

           X_RESOLUTION
                  Some distance/pixel measurement for the  horizontal
                  direction, I think.

           Y_RESOLUTION
                  Some  distance/pixel  measurement  for the vertical
                  direction, I think.

           PLANES Number of color planes for the X server display

           BITS_PER_RGB
                  Number of bits in each rgb triplet.

           CLASS  The X11 visual class, ie PsuedoColor.

           COLOR  Yes or No, Yes if  the  display  class  is  neither
                  The fvwm version number, ie 2.0

           OPTIONS
                  Some  combination of SHAPE, XPM, NO_SAVEUNDERS, and
                  M4, as defined in configure.h at compile time.

           FVWMDIR
                  The directory where fvwm looks for .fvwmrc and mod-
                  ules by default, as determined at compile time.

           FvwmM4  is  the  result of a random bit mutation on a hard

           thing.
