$Id$ -> $FreeBSD$

Revert $FreeBSD$ to $Id$

Add back the description of the "-v" option. It seems to have been
lost in the conflict resolution leading up to revision 1.4.
2.2 candidate.

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Remove the $ Log: ... $ lines from the comments in the files that had
them. Good greif! This was causing an unimaginable amount of brain-damage!
The mere fact that I griped about $ Log $ in a previous commit (misspelled
deliberately here) meant that the blasted thing was being expanded from the
middle of the log entry as well as the beginning, and using " * All these"
as the comment leader.. AARGH!!!! We *really* need to prevent these from
being expanded! (or remove the magic identifier from the source).

Restore phk's changes from 1.3 - 1.5.. Adds a -v switch to rlog to get it
to print the current version of the RCS files.

Restore nate's change from rev 1.2; improve readability of the rlog output
(adds a short row of dashes in a place that CVS and RCS dont mind)

First part of import conflict merge from rcs-5.7 import.

All those $Log$ entries, combined with the whitespace changes are a real
pain.

I'm committing this now, before it's completely finished to get it compiling
and working again ASAP. Some of the FreeBSD specific features are not working
in this commit yet (mainly rlog stuff and $FreeBSD$ support)

Remove trailing whitespace.

typo.

made -v produce tip-revision, which was what I wanted in the first place...

Added -v option to rlog. This gives a quick way to get a list of versions.

Have rlog output be much easier to parse. (Added one line which is not
used by any CVS/RCS commands)

Update makefiles:
centralize obj/noobj conditional in Makefile.inc
use DPADD
don't compile profiling library
install rcsfreeze correctly
After this commit, the freebsd and netbsd rcs distribution will be in sync.

Really cleaned up obj/noobj this time (same as I did with CVS)

Fixed cvs to work with/without object directories and added missing rcslean
directory to top level makefile.

This commit was generated by cvs2svn to compensate for changes in r9,
which included commits to RCS files with non-trunk default branches.
