parse Debian changelogs and output them in other formats

 Parse::DebianChangelog is a replacement for the very limited
 dpkg-parsechangelog. It can be used either via the parsechangelog
 command line script or as Perl module.

 Currently supported output formats:
  * original dpkg-parsechangelog output format
  * similar format with multiple stanzas instead of one
  * XML
  * HTML (customizable via HTML::Template templates).
