# Each plugin is a package that contains the subs:
#
#   initPlugin           ( $topic, $web, $user, $installWeb )
#   commonTagsHandler    ( $text, $topic, $web )
#   startRenderingHandler( $text, $web )
#   outsidePREHandler    ( $text )
#   insidePREHandler     ( $text )
#   endRenderingHandler  ( $text )
#
# initPlugin is required, all other are optional. 
# For increased performance, all handlers except initPlugin are
# disabled. To enable a handler remove the leading DISABLE_ from
# the function name.
