/usr/bin/parsechangelog 1.2.0 Copyright (C) 2005 by Frank Lichtenheld This is free software; see the GNU General Public Licence version 2 or later for copying conditions. There is NO warranty. Usage: parsechangelog [options] [changelogfile] Options: --help, -h print usage information --version, -V print version information --file, -l <file> changelog file to parse, defaults to 'debian/changelog' -F<changelogformat> ignored if changelogformat = 'debian' for compatibility with dpkg-dev -L<libdir> ignored for compatibility with dpkg-dev --format <outputformat> see man page for list of available output formats, defaults to 'dpkg' for compatibility with dpkg-dev --since, -s, -v <version> include all changes later than version --until, -u <version> include all changes earlier than version --from, -f <version> include all changes equal or later than version --to, -t <version> include all changes up to or equal than version --count, -c, -n <number> include <number> entries from the top (or the tail if <number> is lower than 0) --offset, -o <number> change the starting point for --count, counted from the top (or the tail if <number> is lower than 0) --all include all changes If neither "changelogfile" nor "-l <file>" are specified, debian/changelog will be used. If two different files are specified the program will abort. If the filename is "-" the program reads the changelog from standard input. "--all" overrides all other range selecting options. "--count" overrides all other range selection options except for "--all". The range selecting options can be mixed together, but only one of "--since" and "--from" and one of "--until" and "--to" can be specified at the same time. The dpkg and rfc822 formats default to showing only the first entry when no other options are given with while the HTML and XML formats default to showing all entries. For a more extensive documentation of the range selecting options and some (hopefully enlightening) examples see "COMMON OUTPUT OPTIONS" in Parse::DebianChangelog.
