The "official" locker for all versions of 2020 is the locker "2020".  The
sequence:

       add 2020 ; 2020 

will run release 2 of 2020 for the VAX and release 1 of 2020 for the RT.  Note
that the files generated by the different versions are incompatable.  If it is
necessary for someone to read a spreadsheet created on the VAX with 2020
release 1, the command "2020.r1" will give the old release of 2020.  (This
will work on the Vax only).

A tutorial is available for 2020 release 2 only.  This tutorial and the
on-line help have been modified to include the special key definitions
particular to the Athena environment.  To get to it, type:

	add 2020; t2020

One caution: the man page in 2020/man is out of date and has not been revised
for release 2 of 2020.
