tuxedo.pl - find subs in a Z-code file

++

++

This program finds the locations of the subroutines in a Z-code file. Right now, the program is actually used to confirm that the pure Perl parser is working - it compares the results with the results from the state-of-the-art (1992) txd parser, and ...
