Reply: Zack Brown: "Re: lk-changelog.pl 0.96"
This is a semi-automatic announcement.
lk-changelog.pl aka. shortlog version 0.96 has been released.
This script is used by Linus and Marcelo to rearrange and reformat BK
ChangeSet logs into a more human-readable format, and the official
repository is bk://gkernel.bkbits.net/BK-kernel-tools/
The changes are listed at the end of the script below.
You can always download this script and GPG signatures from
http://mandree.home.pages.de/linux/kernel/
My thanks go to Vitezslav Samel who has spent a lot of time on digging
out the real names for addresses sending in BK ChangeSets.
Note that your mailer must be MIME-capable to save this mail properly,
because it is in the "quoted-printable" encoding.
= <- if you see just an equality sign, but no "3D", your mailer is fine.
= <- if you see 3D on this line, then upgrade your mailer or pipe this mail
= <- into metamail.

# * Reset $ENV{PATH} to /bin:/usr/bin:/usr/local/bin for the same reason.
# * In usage information, path-strip $0 in addition to that (and store in

#   entries.
#
# Revision 0.88  2003/03/26 21:12:23  emma

# Recognize "bk changes" output format (that is: "ChangeSet@1.234.5.6,
# date, programmer" tag line and body indented by two spaces). Reported
# by Marcelo Tosatti <marcelo@conectiva.com.br>. Former versions would
# only recognize the BK-kernel-tools/changelog format (see
# http://gkernel.bkbits.net:8080/BK-kernel-tools/anno/changelog@1.5?nav=index.html|src/).
#
# Revision 0.24  2002/06/03 13:33:00  emma
# * Fix 'grouped', 'terse', 'oneline' modes (change to parse_file()). We
#   now take the first paragraph instead of the first line as log
#   entry. We also guess where the paragraph ends, it ends at a line with
#   trailing dot or colon, or if the next line is empty or starts with a
#   "bullet" (that is -, *, o or #).
# * New option --abbreviate-names.
# * Fix 'full' mode indentation, broken in v0.21 by expanding the tabs.
#   Now, the first tab is unexpanded again.
# * Enhance 'online' mode: if the log is truncated, append an ellipsis ("...").
# * Add more mail addresses.
# * Fix Brian Beattie's name (was "Michael Beattie").
#
# Revision 0.23  2002/06/03 12:36:01  emma
# More e-mail addresses.

# Mail addresses added.
#
# Revision 0.21  2002/05/29 11:45:48  emma
# * Implement --mode=oneline.
# * Expand tabs in input lines (tab stops are spaced 8 columns away from each other).
# * Bugfix --multi mode: all append_item to flush @cur before printing.
# * Restore prolog detection in --multi mode for efficiency.
# * Undo the "unexpand()" that Text::Wrap does, it breaks our line width
#   calculation. In the long run, a replacement for Text::Wrap must be
#   found that does not unexpand().
#
# Revision 0.20  2002/05/29 10:44:35  emma
# New --multi option that states multiple changelogs are in the same file.

# Sort addresses/names case insensitively (not locale aware).

# Do not require Pod::Usage, but warn if it's missing.

# Revision 0.14  2002/05/22 12:39:59  emma
# Fold the print function dispatcher into %table.

                     obfuscate "email address" in output
     --[no]ignoremerge
                     suppress "Merge bk://..." changelogs.

     --mode=MODE     specify the output format (use --man to find out more)
     --width[=WIDTH] specify the line length, if omitted: $COLUMNS or 80.
                     text lines will not exceed this length.

     --selftest      perform some self tests (for developers of this script)

Warning: Neither --compress nor --count are currently functional with
--mode=full.

=head1 DESCRIPTION

Summarizes or reformats BitKeeper ChangeLogs for Linux Kernel 2.X.

=head1 ENVIRONMENT

=over

=item LINUXKERNEL_BK_FMT

Default options. These have the same meaning and syntax as the command
line options and are parsed before them, so you can override defaults
set in this variable on the command line. B<Example:> If you put
--swap here and --noswap on your command line, --noswap takes
precedence.

=head1 EXAMPLES

=over

=item Reformat ChangeLog-2.5.17, displaying all changes grouped by
  their author (that is the default mode, but we specify it anyways),
  with 76 character wide lines:

 lk-changelog.pl --mode=grouped --width=76 ChangeLog-2.5.17

=item Reformat ChangeLog-2.5.18, displaying all changes and their
      author on in "-ac changelog style", with 80 character wide lines:

 lk-changelog.pl --mode=terse --width=80 ChangeLog-2.5.18

=item Reformat 2.4.19-pre ChangeLogs (several in one file) from your mailer:

Use the pipe command to pipe the mail into:

 lk-changelog.pl --multi --mode=terse --width=80
