Oh! Now I understand. Seems like you could do something similar to  
what I did. Mine's hard-coded to check for the name of my target, and  
if it sees that, it changes the StringTemplate loader and location to  
get it off a directory of my choosing. The change I proposed should  
make that nicely generalized to all users.
