+=head1 NAME
+
+flavourpathinfo - allows flavour designation via a trailing path component
+instead of via a file extension
+
+=head1 DESCRIPTION
+
+flavourpathinfo is a syntactic sugar plugin that allows flavour designation 
+via a trailing path component instead of via a file extension e.g.
+
+    http://blog.example.com/category/post/html
+    http://blog.example.com/category/post/atom
+    http://blog.example.com/category/post/trackback
+
+instead of the more typical:
+
+    http://blog.example.com/category/post.html
+    http://blog.example.com/category/post.atom
+    http://blog.example.com/category/post.trackback
+
+=head1 USAGE
+
+Should be loaded early as it manipulates $blosxom::path_info
+e.g. as 00flavourpathinfo.
