rsalz@uunet.UU.NET (Rich Salz) (09/29/87)
Submitted-by: chris@nrcvax.uucp (Chris Grevstad)
Posting-number: Volume 11, Issue 84
Archive-name: tcsh.4.3/part01
This stuff is to adapt Paul Placeway's tcsh to BSD4.3 csh.
The files tcsh.DIFF* are to replace the DIFFS* files that got distributed
with the tcsh stuff in volume 10 of comp.sources.unix.
Be sure to replace DIFFS.1 with tcsh.DIFFS.1 and DIFFS.2 with tcsh.DIFFS.2.
At that point you should be able to follow the directions included in the
README file.

+ *
+ * Added scheduled commands, including the "sched" command,
