+Excerpts from the README:
+
+ This is release 1.6 of rc.
+
+ A unix version of the Plan-9 Shell.
+
+ FEEPING CREATURISM
+
+ See the end of the man page, under "INCOMPATABILITIES" for (known?)
+ differences from the "real" rc. Most of these changes were necessary
+ to get rc to work in a reasonable fashion on a real (i.e., commercial,
+ non-Labs) UNIX system; a few were changes motivated by concern
+ about some inadequacies in the original design.
+
+ CREDITS
+
+ This shell was written by Byron Rakitzis, but kudos go to Paul
+ Haahr for letting me know what a shell should do and for contributing
+ certain bits and pieces to rc (notably the limits code, print.c,
+ most of which.c and the backquote redirection code).
