To create and use MFX-Groups, you will need
- makemfx, a tool to create XbW-style metafiles out of
  a single header file; it should be already compiled if you
  have compiled XbW. In any case, 
  
  # cd /xw/csource/makemfx
  # make

  will create that tool. For the format of the header file,
  have a look at 
 
  /xw/csource/makemfx/testmfx.h

  there you will find the only acceptable logical format and
  the supported C-types for variables (mostly int, char and double).

Also have a look at 
  /xw/applications/adder/*.*

  this application uses the automatic creation of MFX groups.
