I just wanted to put this up here so that I can show what I did last night in case it looks like I'm not doing anything (I'm talking to myself in the future by the way. I will forget how busy I was.)

This script txt2link.py, is used by my squidparser to makes links out of all those email addresses and urls in the squid events. Now it's new, it's improved, it's da da dum....SUPERUSEFULL!!!!

import re

""" this was adapted from vagueurl.py -- regular expression to match
    informal URLs in plain text.

    This doesn't do and exact job (it doesn't parse the complete syntax
    of URLs) but it should find URLs that at least start right.
    It looks for the start of an address then gobbles up as many legal URL
    characters as it can find.
