XPL compiler for the ZEROX Sigma 7 computer.

This compiler was written for, and runs on, an XDS Sigma-7 computer,
operating under the GORDO time-sharing system at Lawrence Livermore Laboratory,
Livermore, California.  The principal authors are Charles Wetherell and John
Bolstad.  The XPL sub-monitor was written by Kellogg Booth.  GPL was created
from XPL by John Beatty.

dated August 31, 1970.

The compiler was put into the public domain when it was release to the XEROX
Users Group.
