be extracted to the DIF3D8 subdirectory.  See also the files in the
DOC directory for input specifications.

This version of DIF3D8 was developed on a SUN Solaris workstation 
and was tested at RSICC on the following machines:

 Sun Solaris 2.6 on UltraSparc 60 using f77 5.0 and C/C++ 5.0
 IBM RS/6000 44P model 270 running AIX 4.3.3 with XLF 7.1 and C 5.0


ADDITIONAL NOTES  
December 15, 2003

Because it takes on new options with Workshop 6 Updates 1 and 2, we
no longer use the "-fast" compiler option with f77 on Sun Solaris systems.
Also, suspected optimization problems require special compilation options
for two subroutines:

The following two changes in the BUILD.sh script should be noted when
compiling with Forte Workshop 6 compiler on Sun Solaris systems. Changed 
lines are identified by "# <=====".
