Log Message:
-----------
Fix CVS identifiers: remove "FreeBSD" ids that were never functional
in the KNU/SCOP repository, remove "Idaemons" ids that got frozen at
some random point in the history, add "knu" ids reporting the latest revision
from the KNU/SCOP repo merged into this branch, and add "Id" identifiers
to report the current revision in the SCHWARZE repository.

+TODO list for FreeBSD-CVSweb
+-------------------------------------------------------------------------------
+
+o Tear the code apart, and modularize.
+
+o Ensure that fatal error messages are shown properly when gzip encoding
+ is enabled.
+
+o Use specialized modules from CPAN to do stuff, maybe these would be useful:
+ + Archive::Tar
+ + Archive::Zip
+ + Compress::Zlib
+ + Compress::Bzip2
+ + HTML::Entities
+ + Cvs or VCS::LibCVS
+
+o Integrate/cooperate with various CVS utilities.
+ + cvs2cl <http://www.red-bean.com/cvs2cl/>
+ + cvsplot <http://cvsplot.sourceforge.net/>
+ + CVSps <http://www.cobite.com/cvsps/>
+
+o Limit the number of log entries shown.
+
+o Explore whether we can use cvs for all operations and drop rlog, rcsdiff
+ and friends.
+
+o Find out if it is feasible to provide prune-like functionality, ie. hide
+ empty subdirs.
+
+o Recursive diffs, including support for tags/branches/dates.
+
+o Support for dates in tarballs/zips (in addition to tags/branches).
+
+o Make it possible to pass media type parameters with the content-type
+ query string parameter, for example "Content-Type: text/html; charset=utf-8".
+
+o Make use of String::Ediff (if it's available) configurable in the UI.

+* Improved support for the magic "." (== latest) revision on branches
+ for download, view, and annotate URLs.
+* Improved whitespace handling in "human readable" (HTMLized) diffs.
+* The new cvsweb.conf parameter $DEBUG can be set to a true value in order
+ to enable more output to the web server error log for troubleshooting.
+

+
+* More robust URI escaping, links to paths/filenames containing unusual
+ characters work better now.
+* Visual, accessibility, and CSS class structure improvements.
+* Minor optimizations and bug fixes.
+
+Changes in 3.0.1, released 2004-05-08:

+* Light integration with CVSHistory.
+* CvsGraph invocation is more robust against unexpected cvsgraph.conf settings.
+* Fix download links for non-branch files whose revision number contains 0's.
+* Linking to the latest revision of a file works again using ?rev=(.|HEAD).
+* Improve Enscript file type detection regexps.

+* Other minor enhancements.
+
+Changes in 3.0.0, released 2004-02-26:

+* Fix checkouts from paths where the top level dir starts with a dot.
+* Improved hidden/forbidden file/dir functionality.
+* The minimum supported version of GNU Enscript is actually 1.6.3, and
+ for mod_perl 2, >= 1.99_11 is strongly recommended although it does run
+ to some extent with 1.99_08.
