FvwmCpp - the FVWM Cpp pre-processor FvwmCpp is spawned by fvwm, so no command line invocation will work.
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.
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"
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.
