Currently not, but in 2.0 my plan is to have “mate” (or more likely a  
dedicated shell command) expose a bit of TM functionality to the  
shell, this includes parsing a file and outputting the XML (as one  
can currently get as input from a TM command).

This will make it fairly simple to write scripts (or a framework) for  
testing grammars, something we definitely do want to have :)

One little nicety is that this can also perform benchmarks on  
grammars, reporting which rules the parser spends the most time with  
(making it easier to find problematic rules).
