I'm trying (for the first time ever) to make Textmate do syntax-highlighting.  The files I want to highlight are JUNOS router configuration files.  My beginning grammar is

{ scopeName = 'source.junos';
fileTypes = ( 'junos' );
foldingStartMarker = '\{\s*$';
foldingStopMarker = '^\s*\}';
patterns = (
{ name = 'keyword.other.junos';
match = 'groups|system|chassis|interfaces|forwarding-options|snmp|routing-options|protocols|policy-options|firewall|routing-instances';
},
{ name = 'comment.block.junos';
match = '/\*[^\*]*\*/';
},
);
}

When I set the language to JUNOS, folding works but the keywords or comments stay the default color.  Do I need to do something else to see color highlighting?  (assume nothing is too dumb - I'm a newbie to this)

Assuming I get this working, is there a repository of grammars where I can share it?  And maybe find grammars for other odd languages?
