RARSlave alternative for Linux

Serious usenet downloaders know what a pain it is to verify all the .par's then extract the .rar's
from the download. There are some utils on windows that simplify this task, such as Dldone and rarslave. But I haven't been able to a good one on linux, so i had to code my own. It's a simple php script that verifies/extracts the post under all the sub-directories of the given directory and outputs the complete file in the current directory. For those of you guys that suffer the same as I did can try it out: massrep.php.bz2
