'''A suggested first step''' Is it possible to read the Python code and to establish what the algo is in plain words? ex: Step one: define the variable ----- ---- ''What on '''earth''' is the use of this page? -[jcw]'' ''Don't you know??? [There is a huge need for a diffs module!]'' Ah, of course. Thanks for reminding me. Silly me. Shall I insert the above into wikit? :o) ... -[jcw] ----- [Robert Abitbol] Funny boy! Yeah insert it if Python works in Wikit! As I wrote on the top of this page, the original idea was to try to understand the algorithm here so we could reproduce it in TCL/TK. But hey Jean-Claude, I have got other fish to fry you know. If you don't appreciate my ideas and suggestions well what the hell, I won't give them to you and I'll say: "asta la vista babe. I have other more important stuff to do with my life anyway." And that is exactly what I'll do: I'll just continue my navigating on the Internet. Asta la vista babe! PS: I just didn't like the concept here. '''King Jean-Claude and his gang of croonies'''. This reminded me too much of teenie-bopper forums. This place is definitely not for me! -----
