#dumppef

Dumps the contents of a MacOS PEF object file. Its aim(*) is to dump symbol information in a format somewhat like GNU nm(1).

It does no input file validation and barely any error checking, as such it will probably start your keyboard on fire, at best, or overcook your pancakes, at worst.

(*) it absolutely does nothing of the sort, at the moment.
