[BiO BB] Program for superposition of 3D point sets

[Skull Crossbones]

Check this:
http://boscoh.com/protein/matchpy

This is a python program, which accepts a set of equivalent 'atoms'.
I beleive this can be modified easily to accept co-ordinates of the equivalent points to be superposed, instead of reading from a pdb file
