Ok, thanks for confirming this was a possibility.

I actually asked him, to be sure, and that's what he told me as well,
that he simply translated into Python.

I removed the jsmin tools from the source tarball of OpenLayers and
rebuilt it for F-11 and Rawhide (I don't have the commit access in
F-10, and it will be EOL-ed soon anyway, if that really matters I'll
ask for the commit ACL and do it there as well).

In the future, I'll try to see if another Javascript minifier couldn't
be used instead of jsmin and what the OpenLayers devs think about it.
