Simple Perl script for formatting code for posting
This script formats program listings for posting in the site.
It takes two arguments, the name of the file and optionally a number for TAB size. If the TAB size is ommited, it is assumed to be 8.
The script replaces all TABs by a number of spaces sufficient for the next character begin in a column multiple of the TAB size plus 1. It replaces also all "&" by "&" and all "<" by "<".
