301 Redirecting URLs Based on GET Variables in .htaccess

Question

I have some dirty old urls like ...

http://www.example.com/bunch.of/unneeded/crap?opendocument&part=1

http://www.example.com/bunch.of/unneeded/crap?opendocument&part=2

... what I want to redirect to a newer, cleaner form ...

http://www.example.com/page.php/welcome

http://www.example.com/page.php/prices

I understand that I can redirect one page to another with a simple redirect i.e.

Redirect 301 / bunch.of / unneeded / crap http://www.example.com/page.php

But the original page does not change, only it is GET vars. I cannot figure out how to set the redirection to the value of these GET variables. Can someone help pls !? I am pretty comfortable with old regular expressions, so I can use pop-rewrite if I have to, but I don’t understand the syntax for rewriting GET vars, and I would rather avoid a performance hit and use the pure Redirect directive. Is there any way? and if not, can anyone understand me regarding the correct pl-rewrite syntax?

Greetings

Roger.
