i'm almost surpised i havn't found a script that just take another script and adds a couple global variables, inserts Benchmarks at the beginning and end of all subs, and prints out the results of that. It would be rude and crude, but would seem fairly practical, and do profiling w/o relying on anything low-level.

Of course i could be wrong, in that either it does exist, or it wouldn't be practical....
