Converting a patch to an ordinary changeset

[Konrad Hinsen]

I have been developing an experimental modification of a library as a  
patch managed by MQ. Now I am happy with that modification and I  
would like to integrate it in the main repository. What I want to do is

1) Apply the patch.
2) Remove the patch from the patch queue maintained by MQ.
3) Commit the effect of the patch to the repository.

This looks common enough that it ought to be simple, but I haven't  
found a simple way to do it. Any ideas?

Thanks in advance,
   Konrad.
