Add an "iso8601" option keyword which causes 'cvs log' etc. to print
dates in ISO 8601 format.

Initial merge of cvs-1.11.5 -> 1.11.15 changes onto mainline

Add "blame" as an "annotate" alias for interoperability with subversion.

Initial merge of 1.11.1p1 -> 1.11.2 changes onto mainline

Initial merge of cvs-1.11 -> 1.11.1p1 changes onto mainline. There is
still some suspicious and/or broken stuff to fix yet.

Merge changes from 1.10.7 -> 1.11 into mainline. Note that the old
anoncvs no-password hack is gone and is replaced by the official version.

Merge cyclic changes from 1.10.7 into our mainline. I did this seperately
as cvs update -j had kittens over the whole thing and I ended up merging
it by hand.

Support the environtmental var "CVS_OPTIONS". Which can hold a set of
default options for cvs. These options are interpreted first and can be
overwritten by explicit command line parameters.

Merge cvs-1.9.xx -> 1.10 changes onto mainline.

Changes of significance include the top level CVS directory being optional
and defaulting to off..

Fixed typo in previous commit. oops.

Add '-g' main option to cvs to better support shared-group access
to a common checked-out *working* set by multiple users. See manual
page for details.

Add a new long flag that causes cvs to ignore the CVSROOT/passwd file.
This is mostly intended for use on freefall where we'd like to provide
a passwd file for easy anoncvs mirroring access, but don't want to open
up the pserver on freefall itself.

While here, some initial tweaks intended for allowing an empty pserver
password. I'm not sure that this works yet.

Merge changes from vendor branch into mainline

Cosmetic cleanups for the local tag support. Since rcs isn't called
anymore, don't do all the putenv's for it's benefit.

Merge changes from CYCLIC branch onto mainline. rcs.[ch] still to come.

Implement a -R option to cvs to turn on read-only repository mode.
When using a local repository that is only written to by CVSup - which
I assume doesn't do the cvs locking protocol - this option might be a
speedup since cvs will not create lock files.

Pull in OpenBSD's support for checking out from a read-only repository,
such as within an anoncvs server, or from a CDROM repository.
Cyclic (the cvs maintainers) do not like this approach and have an
alternative read-only system, but that requires a read/write repository to
work (which rules out CDROM).

Complete the support for $FreeBSD$. Add an option "tagexpand=" which
controls the RCSINCEXC encironment variable for our rcs version, and
also convert the rest of the checkout enhancements from rcs into cvs's
fast checkout code. (yes, cvs doesn't call 'co' anymore)
We now have fine grained individual keyword expansion control and can
set the keyword to anything the user wants.

Also, a new keyword, $CVSHeader$ comes in from rcs, it's like $Header$
except that it shows the pathname relative to the cvsroot. eg:
$FreeBSD: src/bin/ls/ls.c,v 1.10.2.14 1997/05/17 13:15:45 peter Exp $
^^^^^^^^^^^^^^^^^
The idea for this comes from $XFree86$ which expands like $CVSHeader$.
The "local id" string can be set to expand like Id, Header or CVSHeader.
(Matching support for this is apparently happening in cvsup right now)

Initial round of support for a local $Id$ keyword in cvs, eg: $FreeBSD$.
This is not complete yet in that it doesn't drive our version of RCS
completely, but it does work fine when you do the appropriate magic.

Fix a bug in the "cvs init" command. It ignored the global "-H" option.
I.e., "cvs -H init" went ahead and initialized the repository, and did
not print out a usage message. Not nice.

Also added the "init" command to the list that comes out when you type
"cvs --help-commands". There is still not a word about it in the manual
page.

Yes, I am sending these fixes to the FSF.
