What conversion do you expect? The docs say it clearly that the eclass
will be extended on request, so please file a clear request what you
want with an example use case.

There is python_export(). I will be happy to extend it / add
python_get*() wrappers when someone makes a clear list of what
is needed.

Example use cases will be appreciated again. Good examples will make it
possible to choose good variable names.

There is a lot of stuff missing for packages which try to install
Python stuff by hand rather than using proper setup. I will be happy to
provide more when I know what is actually needed and how it will be
used.

It's a quick function. Adding additional paths or changing
the algorithm won't be hard. Just don't expect me to do random stuff
just because someone may want that someday.

FYI: I've added that mindless games/bin to the paths.

inherit python-r1

RDEPEND='gtk? ( ${PYTHON_DEPS} )'

There are side effects and they are well known. Still, none of them is
an issue important enough to outweigh the benefit.

You would use the function I would introduce when I got the request
filed and potential discussion done. Most importantly, whether there
should be a way to call 2to3 on the scripts.

By the way, did you just request two partial features instead
of requesting a way to manually install Python scripts?

Thanks. I will take a look at that package and see what is necessary to
make it buildable with python-r1.

By the way, do I understand correctly that right now you are building
stuff for a random Python implementation and removing it afterwards?
I believe that's something really worth fixing.
