Should ``csh'' be part of the System V distribution?

Well, no, you really can't, not always.  There are supposedly a few real live
incompatibilities that may break some scripts.

The only ones that are standard with S5R3 are: "sh" (obviously), "the new
make" if this refers to the S5 "make" (neither "nmake" nor "mk" are part of
S5R3), and the "plot" stuff (PLOT(5) describes the format - AT&T calls this man
page PLOT(4); according to the S5R3 man pages, the "plot" command is there,
under the name of "tplot", and the "plot" library is there, but it supports
fewer devices than 4.3BSD does).

The new "awk" is standard with S5R3.1.  *None* of the formatting stuff is
standard with S5R3 of any flavor; this includes "ditroff", "pic", and all the
aforementioned macro packages.  It's all part of DWB, which provides "-mm" but
neither "-ms" nor "-me".

Of course, just because AT&T doesn't make something standard with *their*
releases doesn't mean everybody else is obliged to unbundle it.  They can
bundle it, as long as they pay AT&T all the requisite licensing fees for all
the code in question (DWB requires a separate license, as does "ksh"; "csh" and
"-me" don't, and I guess "-ms" doesn't because it's covered by your base UNIX
license, having been a part of older AT&T releases).
