MAKE/VMS is no longer supported since MMK (MMS clone by Matt Madison/MadGoat
Enterprises, compatible with descrip.mms) is both free and becoming quite
popular.  MMK is available by anonymous ftp from ftp.spc.edu/ftp.wku.edu and
by mailserver at lists.wku.edu.  Check VMS newsgroups for announcements and
exact location.

Detailed compilation and installation instructions can be found in the
INSTALL.VMS file in this directory.
