[TxMt] Bundle command to import from external file

[Ben Smith]

I'd like to set-up a command to import text from an external txt/html/ 
js to a current project but have had no luck finding any tips on how  
to go about this. Is it possible?
I think it would be really handy to have for example a command that  
pulled in the latest swfobject.js from my SVN repositories. I'm sure  
this could be useful for lots of other workflow timesavers too.
