mkcmd lets us build a nifty command line option parser and some
on-line documentation in a snap. It is a prerequisite for many of
Kevin Braunsdorf's tools.
Remove expired port and two leaf ports that depend on it:
2019-03-31 devel/msrc0: No longer required as comms/conserver is being retired.
devel/mkcmd
sysutils/curly
For ports that have an EXPIRATION_DATE which has already passed, but
that have other ports that depend on them, mark the ports that depend
on them DEPRECATED, and make all EXPIRATION_DATEs 2011-10-31.
For ports maintained by ports@FreeBSD.org, remove names and/or
e-mail addresses from the pkg-descr file that could reasonably
be mistaken for maintainer contact information in order to avoid
confusion on the part of users looking for support. As a pleasant
side effect this also avoids confusion and/or frustration for people
who are no longer maintaining those ports.
