In about 1982 LR was available for a nominal fee from the National Energy
Software Center located at Argone National Laboratory. I used a copy to
write my masters thesis.


The system is described in:


Wetherall, Charles and Alfred Shannon, "LR - Automatic Parser
Generator and LR(1) Parser," IEEE Transactions on Software
Engineering SE-7, 3, 274-278, May 1981.


The tables are meant to be transportable, so they are not packed at all.
I spent some time packing the tables and extending the grammar so that it
would be tolerable to use.


I have a copy somewhere on a 9-track tape in DEC-10 backup format, but
since I have neither a DEC-10, a 9-track tape drive nor any desire to look
for it, please don't ask.
