[TxMt] new bundle from Sweave and markdown

[Charilaos Skiadas]

Hi Baptiste,

	you are probably not too far, I assume you have read chapter 12 from  
the manual carefully? If not, I think that would be the key missing  
piece:
http://macromates.com/textmate/manual/ 
language_grammars#language_grammars

This should tell you about meanings of all those weird words here and  
there, like "match", "pattern", . The only other piece missing is  
regular expressions. In particular, you would have to change the  
places were << and @ were matched to the new correct things. Looking  
at how Erb does that might help (hm, I've been out of touch with TM  
development for a while, where are the rules for matching <% ... %>  
in erb files?).

I wrote the syntax a while back, but I don't think anyone has  
modified it since. I'm a bit rusty on it atm, but feel free to pick  
my brain if/when you get stuck.
