I still need to write the docs unfortunately.

Basically it does a grep for a prefix (defaulting to "CHECK:") and  
verifies that the strings occur, and in order.  Take a look at CodeGen/ 
arm/mul_const.ll for a simple example.  It also defaults to  
canonicalizing horizontal whitespace, so you don't have to do an exact  
match on tabs and spaces.

One annoying current limitation is that it doesn't support regex's yet.
