I gave an example in an earlier post.  This is a typical assignment statement

(<1>..<14639> & /master/b) | /premerge-fsf-branch/b assign gcc2 

It binds a name, gcc2, to a selection set of revisions.  Subsequently the
reosurgeon minilanguage will recognize <gcc2> anywhere it would take
a selection-set expression.

For more about how to compose these, see the reposurgeon manual:

I don't have an automated way to do this.  The reposurgeon minilanguage
has the ability to look inside ChangeLog blobs, but it doesn't have
the control structures that would be required to do what you are suggesting.

Somebody would need to write a custom Python extension to reposurgeon,
and that somebody would probably have to be me.  It seems like a lot
of work to do something that throws away having a 1:1 ID to contributor
mapping.

Is there any way to identify changes to a port by the paths of the
modified filenames? If so, this would get much easier.
