23 # * INPUT is the input file
24 # * OUTPUT is file PROG generates
25 # * DESIRED is file we actually want
26 # * ARGS are passed to PROG
27 # Any number of OUTPUT,DESIRED pairs may be used.

41 # Relative path. Make it absolute. Why? Because otherwise any
42 # debugging info in the generated file will point to the wrong
43 # place. This is really gross.
