After  uncompressed  file xgam.tar.Z,   three seperate directories will
be created:

xjc ----------- library for xgam
prog ---------- xgam source files
yap17 --------- display 3D cube and 2D slice

NOTE: GSLIB utility library is required to compile these programs.
      the GSLIB library file libgs.a is assumed to reside in ../../gslib/

To install xgam, type "./install", then the executive program will be
found in prog directory. 

After that, please append Xgam in prog directory and yap.ad in yap17 
directory to your  ~/.Xdefaults and run "xrdb ~/.Xdefaults".
