           FvwmCpp - the FVWM  Cpp pre-processor

## SYNOPSIS

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

## DESCRIPTION

           When called, this module will attempt to have /usr/lib/cpp
           pre-process the file specified in its invocation, and then
           have fvwm read the resulting file.

## INVOCATION

           FvwmCpp can be invoked by inserting the line 'FvwmCpp'  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 FvwmCpp, then fvwm should be invoked as
           "fvwm -f /usr/lib/X11/fvwm/FvwmCpp

           Some options can be specified on the command line:

           -Cppopt
                  Lets you pass an option to the cpp program.

           -Cppprog
                  Instead  of  invoking  "/usr/lib/cpp",  fvwm   will
                  invoke name.

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

## CONFIGURATION OPTIONS

           FvwmCpp  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

           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
                  StaticGrey or GreyScale.

           FVWM_VERSION
                  The fvwm version number, ie 2.0

           OPTIONS
                  Some combination of SHAPE, XPM, NO_SAVEUNDERS,  and
                  Cpp, 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.
