Lcrzo is GPL network testing app

Network Software: 400 Pieces and Counting With Cross-Platform Net Tester lcrzoex

It looks like it is comprehensive. The numeric command switches are unique I haven't seen that before in a command line utility...numbers yes, but calling different options by sequential numbers?

If you like those big toolsets from Sears that contain hundreds of pieces- and what's not to like, more = better- you'll love lcrzoex, the 400+ piece network testing toolbox. The author calls it "Swiss Knife For Network Developers."

Written by Laurent Constantin, it runs on *nix and Windows. I wish Mr. Constantin had authored a catchier name, but what the heck, it's his program. I quote from the lcrzo docs: "Lcrzo, which means "Laurent Constantin RHZO" (RHZO=network in French), can be pronounced " 'el' 'sea' 'reso'lv". Mr. Constantin was kind enough to provide an English translation of all the documentation.
