There are two MIT-specific pathnames which must be overridden before
using xdsc in a new environment.  This can be done either via environment
variables at runtime, or by changing the values in xdsc.c and compiling.

If the environment variable XFILESEARCHPATH isn't set, xdsc looks for its
app-defaults file, "Xdsc," in "/mit/StaffTools/lib/X11/app-defaults/%N" 
which probably won't exist outside of MIT.  Set the value of XFILESEARCHPATH
in your environment pointing to the home of the app-defaults file, or change
the default path in the code.

Xdsc runs a co-process, "edsc," which does the actual talking with the 
discuss servers.  If the environment variable EDSC isn't set, it looks for
edsc in "/mit/StaffTools/*bin/edsc".  Find edsc's home on your system, and
either set your environment variable or change the pathname in the code.
