-# 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
- -t, --tags Show tags (symbolic names) in output
- --stdin Read from stdin, don't run cvs log
- --stdout Output to stdout not to ChangeLog
- -d, --distributed Put ChangeLogs in subdirs
- -f FILE, --file FILE Write to FILE instead of "ChangeLog"
- --fsf Use this if log data is in FSF ChangeLog style
- -W SECS, --window SECS Window of time within which log entries unify
- -U UFILE, --usermap UFILE Expand usernames to email addresses from UFILE
- -R REGEXP, --regexp REGEXP Include only entries that match REGEXP
- -I REGEXP, --ignore REGEXP Ignore files whose names match REGEXP
- -C, --case-insensitive Any regexp matching is done case-insensitively
- -F BRANCH, --follow BRANCH Show only revisions on or ancestral to BRANCH
- -S, --separate-header Blank line between each header and log message
- --no-wrap Don't auto-wrap log message (recommend -S also)
- --gmt, --utc Show times in GMT/UTC instead of local time
- --accum Add to an existing ChangeLog (incompat w/ --xml)
- -w, --day-of-week Show day of week
- --header FILE Get ChangeLog header from FILE ("-" means stdin)
- --xml Output XML instead of ChangeLog format
- --hide-filenames Don't show filenames (ignored for XML output)
- -P, --prune Don't show empty log messages
- -g OPTS, --global-opts OPTS Invoke like this "cvs OPTS log ..."
- -l OPTS, --log-opts OPTS Invoke like this "cvs ... log OPTS"
- FILE1 [FILE2 ...] Show only log information for the named FILE(s)

-=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.
-
-Maintainer: Karl Fogel <kfogel@red-bean.com>

-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...
