=head1 Name

SVN::Notify::Filter::Trac - Filter SVN::Notify output in Trac format

=head1 Synopsis

Use F<svnnotify> in F<post-commit>:

  svnnotify --p "$1" --r "$2" --to --handler HTML \
  --filter Trac --trac-url

Use the class in a custom script:

  use SVN::Notify;

  my $notifier = SVN::Notify->new(
      repos_path => $path,
      revision   => $rev,
      to         => '',
      handler    => 'HTML::ColorDiff',
      filters    => [ 'Trac' ],
      trac_url   => '',

=head1 Description

This module filters SVN::Notify log message output from Trac markup into HTML.
Essentially, this means that if you write your commit log messages using Trac
wiki markup and like to use L<SVN::Notify::HTML|SVN::Notify::HTML> or
L<SVN::Notify::HTML::ColorDiff|SVN::Notify::HTML::ColorDiff> to format your
commit notifications, you can use this filter to convert the Trac formatting
in the log message to HTML.

If you specify an extra argument, C<trac_url> (or the C<--trac-url> parameter
to C<svnnotify>), it will be used to generate Trac links for revision numbers
and the like in your log messages.
