-# Usage:
-#     ylwrap PROGRAM [ARGS] INPUT [OUTPUT DESIRED]... -- [-yy repl] [ARGS]...
-# * PROGRAM is program to run; options can follow but must start with `-'.
-# * INPUT is the input file
-# * OUTPUT is file PROG generates
-# * DESIRED is file we actually want
-# * ARGS are passed to PROG
-# * Optional -yy introduces the sequence to replace yy prefixes with.
-# Any number of OUTPUT,DESIRED pairs may be used.
-
-# The program to run.
-prog="$1"

-# Make any relative path in $prog absolute.

-# We also have to accept options here and append them to the program.
-# Why?  Suppose YACC is set to `bison -y'.  Clearly nobody uses
-# ylwrap, or this would have been discovered earlier!
