-# The Plan:
-#
-# Read in the logs for multiple files, spit out a nice ChangeLog that
-# mirrors the information entered during `cvs commit'.
-#
-# The problem presents some challenges. In an ideal world, we could
-# detect files with the same author, log message, and checkin time --
-# each <filelist, author, time, logmessage> would be a changelog entry.
-# We'd sort them; and spit them out.  Unfortunately, CVS is *not atomic*
-# so checkins can span a range of times.  Also, the directory structure
-# could be hierarchical.
-#
-# Another question is whether we really want to have the ChangeLog
-# exactly reflect commits. An author could issue two related commits,
-# with different log entries, reflecting a single logical change to the
-# source. GNU style ChangeLogs group these under a single author/date.
-# We try to do the same.
-#
-# So, we parse the output of `cvs log', storing log messages in a
-# multilevel hash that stores the mapping:
-#   directory => author => time => message => filelist
-# As we go, we notice "nearby" commit times and store them together
-# (i.e., under the same timestamp), so they appear in the same log
-# entry.
-#
-# When we've read all the logs, we twist this mapping into
-# a time => author => message => filelist mapping for each directory.
-#
-# If we're not using the `--distributed' flag, the directory is always
-# considered to be `./', even as descend into subdirectories.

-Generate GNU-style ChangeLogs in CVS working copies.
-
-Notes about the output format(s):
-
-   The default output of cvs2cl.pl is designed to be compact, formally
-   unambiguous, but still easy for humans to read.  It is largely
-   self-explanatory, I hope; the one abbreviation that might not be
-   obvious is "utags".  That stands for "universal tags" -- a
-   universal tag is one held by all the files in a given change entry.
-
-   If you need output that's easy for a program to parse, use the
-   --xml option.  Note that with XML output, just about all available
-   information is included with each change entry, whether you asked
-   for it or not, on the theory that your parser can ignore anything
-   it's not looking for.
-
-Notes about the options and arguments (the actual options are listed
-last in this usage message):
-
-  * The -I and -F options may appear multiple times.
-
-  * To follow trunk revisions, use "-F trunk" ("-F TRUNK" also works).
-    This is okay because no would ever, ever be crazy enough to name a
-    branch "trunk", right?  Right.
-
-  * For the -U option, the UFILE should be formatted like
-    CVSROOT/users. That is, each line of UFILE looks like this
-       jrandom:jrandom@red-bean.com
-    or maybe even like this
-       jrandom:'Jesse Q. Random <jrandom@red-bean.com>'
-    Don't forget to quote the portion after the colon if necessary.
-
-  * Many people want to filter by date.  To do so, invoke cvs2cl.pl
-    like this:
-       cvs2cl.pl -l "-d'DATESPEC'"
-    where DATESPEC is any date specification valid for "cvs log -d".
-    (Note that CVS 1.10.7 and below requires there be no space between
-    -d and its argument).
-
-Options/Arguments:
-
-  -h, -help, --help, or -?     Show this usage and exit
-  --version                    Show version and exit
-  -r, --revisions              Show revision numbers in output
-  -b, --branches               Show branch names in revisions when possible

-=head1 NAME
-
-cvs2cl.pl - produces GNU-style ChangeLogs in CVS working copies, by
-    running "cvs log" and parsing the output.  Shared log entries are
-    unified in an intuitive way.
-
-=head1 DESCRIPTION
-
-This script generates GNU-style ChangeLog files from CVS log
-information.  Basic usage: just run it inside a working copy and a
-ChangeLog will appear.  It requires repository access (i.e., 'cvs log'
-must work).  Run "cvs2cl.pl --help" to see more advanced options.
-
-See http://www.red-bean.com/cvs2cl for updates, and for instructions
-on getting anonymous CVS access to this script.

-Note about a bug-slash-opportunity:
------------------------------------
-
-There's a bug in Text::Wrap, which affects cvs2cl.  This script
-reveals it:
-
-  #!/usr/bin/perl -w
-
-  use Text::Wrap;
-
-  my $test_text =
-  "This script demonstrates a bug in Text::Wrap.  The very long line
-  following this paragraph will be relocated relative to the surrounding
-  text:
-
-  ====================================================================
-
-  See?  When the bug happens, we'll get the line of equal signs below
-  this paragraph, even though it should be above.";
-
-  # Print out the test text with no wrapping:
-  print "$test_text";
-  print "\n";
-  print "\n";
-
-  # Now print it out wrapped, and see the bug:
-  print wrap ("\t", "        ", "$test_text");
-  print "\n";
-  print "\n";
-
-If the line of equal signs were one shorter, then the bug doesn't
-happen.  Interesting.
-
-Anyway, rather than fix this in Text::Wrap, we might as well write a
-new wrap() which has the following much-needed features:
-
-* initial indentation, like current Text::Wrap()
-* subsequent line indentation, like current Text::Wrap()
-* user chooses among: force-break long words, leave them alone, or die()?
-* preserve existing indentation: chopped chunks from an indented line
-  are indented by same (like this line, not counting the asterisk!)
-* optional list of things to preserve on line starts, default ">"
-
-Note that the last two are essentially the same concept, so unify in
-implementation and give a good interface to controlling them.
-
-And how about:
-
-Optionally, when encounter a line pre-indented by same as previous
-line, then strip the newline and refill, but indent by the same.
-Yeah...
