platforms.

>Some time ago I began to notice that many of the wonderful new features added

>  loading advertising content were making web viewing something akin to trying
>  to read a novel in the middle of Times Square on New Years Eve!

>I decided to try and create a general purpose solution - one that could not

>the future. Thus the Proxomitron was born! At it's heart is a powerful text
>  matching engine. Similar to wildcards and regular expressions, but specially
