       cvs2cl - convert cvs log messages to changelogs


       cvs2cl [options] [FILE1 [FILE2 ...]]


       cvs2cl produces a GNU-style ChangeLog for CVS-controlled sources by
       running "cvs log" and parsing the output. Duplicate log messages get
       unified in the Right Way.

       The default output of cvs2cl is designed to be compact, formally
       unambiguous, but still easy for humans to read.  It should be largely
       self-explanatory; 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.

       If filenames are given as arguments cvs2cl only shows log information
       for the named files.


       -h, -help, --help, -?
           Show a short help and exit.

           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.

       -T, --tagdates
           Show tags in output on their first occurance.

           Show dead files.

           Read from stdin, don’t run cvs log.

           Output to stdout not to ChangeLog.

       -d, --distributed
           Put ChangeLogs in subdirs.

       -f FILE, --file FILE
           Write to FILE instead of ChangeLog.

           Use this if log data is in FSF ChangeLog style.

           Attempt strict FSF-standard compatible output.

       -W SECS, --window SECS
           Window of time within which log entries unify.

       -U UFILE, --usermap UFILE
           Expand usernames to email addresses from UFILE.

       --passwd PASSWORDFILE
           Use system passwd file for user name expansion.  If no mail domain
           is provided (via --domain), it tries to read one from
           /etc/mailname, output of hostname -d, dnsdomainname, or domain-
           name.  cvs2cl exits with an error if none of those options is
           successful. Use a domain of ’’ to prevent the addition of a mail

       --domain DOMAIN
           Domain to build email addresses from.

           Get user information from GECOS data.

       -R REGEXP, --regexp REGEXP
           Include only entries that match REGEXP.  This option may be used
           multiple times.

       -I REGEXP, --ignore REGEXP
           Ignore files whose names match REGEXP.  This option may be used
           multiple times.  The regexp is a perl regular expression.  It is
           matched as is; you may want to prefix with a ^ or suffix with a $
           to anchor the match.

       -C, --case-insensitive
           Any regexp matching is done case-insensitively.

       -F BRANCH, --follow BRANCH
           Show only revisions on or ancestral to BRANCH.

       --follow-only BRANCH
           Like --follow, but sub-branches are not followed.

           When using -F, only track changes since the BRANCH started.

           By default, entries generated by cvs for a file added on a branch
           (a dead 1.1 entry) are not shown.  This flag reverses that action.

       -S, --separate-header
           Blank line between each header and log message.

           Add CVS change summary information.

           Don’t auto-wrap log message (recommend -S also).

           Don’t indent log message

       --gmt, --utc
           Show times in GMT/UTC instead of local time.

           Add to an existing ChangeLog (incompatible with --xml).

       -w, --day-of-week
           Show day of week.

           Don’t show times in output.

           Output log in chronological order (default is reverse chronological

       --header FILE
           Get ChangeLog header from FILE ("-" means stdin).

           Output XML instead of ChangeLog format.

       --xml-encoding ENCODING.
           Insert encoding clause in XML header.

           Don’t include xmlns= attribute in root element.

           Don’t show filenames (ignored for XML output).

           Don’t shorten directory names from filenames.

       --rcs CVSROOT
           Handle filenames from raw RCS, for instance those produced by "cvs
           rlog" output, stripping the prefix CVSROOT.

       -P, --prune
           Don’t show empty log messages.

           Output the number of lines added and the number of lines removed
           for each checkin (if applicable). At the moment, this only affects
           the XML output mode.

       --ignore-tag TAG
           Ignore individual changes that are associated with a given tag.
           May be repeated, if so, changes that are associated with any of the
           given tags are ignored.

       --show-tag TAG
           Log only individual changes that are associated with a given tag.
           May be repeated, if so, changes that are associated with any of the
           given tags are logged.

       --delta FROM_TAG:TO_TAG
           Attempt a delta between two tags (since FROM_TAG up to and
           including TO_TAG).  The algorithm is a simple date-based one (this
           is a hard problem) so results are imperfect.

       -g OPTS, --global-opts OPTS
           Pass OPTS to cvs like in "cvs OPTS log ...".

       -l OPTS, --log-opts OPTS
           Pass OPTS to cvs log like in "cvs ... log OPTS".

       Notes about the options and arguments:

       ·   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:


           or maybe even like this

                  jrandom:’Jesse Q. Random <>’

           Don’t forget to quote the portion after the colon if necessary.

       ·   Many people want to filter by date.  To do so, invoke cvs2cl like

                  cvs2cl -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).

       ·   Dates/times are interpreted in the local time zone.

       ·   Remember to quote the argument to ‘-l’ so that your shell doesn’t
           interpret spaces as argument separators.

       ·   See the ’Common Options’ section of the cvs manual (’info cvs’ on
           UNIX-like systems) for more information.

       ·   Note that the rules for quoting under windows shells are different.

       ·   To run in an automated environment such as CGI or PHP, suidperl may
           be needed in order to execute as the correct user to enable
           /cvsroot read lock files to be written for the ’cvs log’ command.
           This is likely just a case of changing the /usr/bin/perl command to
           /usr/bin/suidperl, and explicitly declaring the PATH variable.


       Some examples (working on UNIX shells):

             # logs after 6th March, 2003 (inclusive)
             cvs2cl -l "-d’>2003-03-06’"
             # logs after 4:34PM 6th March, 2003 (inclusive)
             cvs2cl -l "-d’>2003-03-06 16:34’"
             # logs between 4:46PM 6th March, 2003 (exclusive) and
             # 4:34PM 6th March, 2003 (inclusive)
             cvs2cl -l "-d’2003-03-06 16:46>2003-03-06 16:34’"

       Some examples (on non-UNIX shells):

             # Reported to work on windows xp/2000
             cvs2cl -l  "-d"">2003-10-18;today<"""

       Please report bugs to "".


       This script requires "Text::Wrap", "Time::Local", and "File::Basename".
       It also seems to require "Perl 5.004_04" or higher.


       Should work on any OS.
