+""" Mailing-list search plugin for Trac
+  This plugin relies on a working swish-e index for mailing-list.
+  See for example:
+  http://svn.rot13.org/index.cgi/swish/view/trunk/mailman/index_mailman.pl
+  (assuming the archives are generated by pipermail)
+  
+  It also requires the swish-e python wrapper from 
+  http://py-swish-e.berlios.de/
+  
+  The configuration is static in this file for now, it might be moved to 
+  configuration file or an admin panel later. Each mailing-list is defined by:
+  ( short name, index file, label ).
