# Myriad Music Plug-in WikiMedia extension
# 
# http://meta.wikimedia.org/w/index.php?title=Myriad
# 
# Tag :
#   <myriad>uploaded filename.myr or .mus or .mu3|options</myriad>
# Requires :
#   Myriad Music plug-in installed on users' computers.
# Platforms :
#   Windows 95 to XP, Mac OS8 to OSX, maybe Linux through Wine (not tested)
# Browsers :
#   mostly all : IE 4+, Netscape 4+, Mozilla, Opera, K-Meleon, ICab, Safari, Camino...

# 
# Myriad Music plug-in display, allow to play, print, zoom, transpose
# tunes created with Harmony Assistant and Melody Assistant.
# 
# Harmony Assistant is a software for computer-assisted music composition
# and editing, with powerful harmonizing capabilities.
# For me, its most unbeatable feature is the quality of the sound, instead
# of MIDI, Harmony Assistant uses a numeric sound bank.
# The one packaged in the downloadable plug-in is very tiny : about 600 KB.
# The biggest one, the best quality, is sold on CD-Rom and called "Gold".
# A medium quality 6MB sound bank is downloadable at 
# http://www.myriad-online.com/en/resources/extbase.htm
# Harmony Assistant imports MusicXML.
# Melody Assistant is a shareware, with less features.
# 
# To activate the extension :
# - include it at the end of your LocalSettings.php : include("extensions/myriad.php");
# - add .myr, .mus and .mu3 in the extension list :
#   $wgFileExtensions = array('png','gif',...,'myr','mus','mu3');
# 
# If you want to translate the 2 messages in your language, go to
# http://yoursite/wiki/index.php?title=MediaWiki:myriadbeforeplugin
# and http://yoursite/wiki/index.php?title=MediaWiki:myriadafterplugin
# You can also change the default values for height and width in MediaWiki
# namespace or in this file.
# 
# For a complete list of parameters between tags, see the
# "Myriad Music Plug-In Web Designer manual"
# at http://www.myriad-online.com/en/docs/plugdoc.htm
# e.g. <myriad>file.myr|autoplay=on|look=moon</myriad>
# 
# Enjoy !
# 
# For those who want to create extension, you may be interested to look how
# I manage uploaded file (throught Image object), and also how to store default
# messages in the MessageCache (addMessage), and get them from the MediaWiki
# namespace or the MessageCache (wfMsg).
