  * Add support for regexp-based replacing.
  Add an option to replace text in the summary, using regexps. This allows you
  to configure darcsweb to automatically detect and put links to other commits
  or bug numbers.
  
  This patch is heavily based on the one written by Kirill Smelkov
  (kirr@mns.spb.ru).
