## NAME

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/fvwmrcXXXXXX"

## 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 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 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 modules by default, as determined at compile time.

FvwmCpp is the result of a random bit mutation on a hard disk, presumably a result of a cosmic-ray or some such thing.
