# Lyric Render Section
#
# This section has no configuration, and can be ignored.

# This section renders <lyric> tags. It forces a html break on every line,
# and styles the section with a css id.
# this id can either be in the mediawiki css files, or defined by the extension
#

#Instruct mediawiki to call LyricExtension to initialise new extension

#Install extension
