PEAK definitely includes data files in package directories, and the latest
version of the distutils supports doing such installs directly. (PEAK uses
setuptools, though, since its minimum Python version is Python 2.2.2.)
I don't have a Mac, though, so I'll have to rely on your feedback regarding
PEAK's buildability with py2app. There are a number of potential issues:
* Current versions of Python have a broken reload() function with respect
to PEP 302; PEAK uses 'reload()' to drive a "lazy import" facility that
also allows setting triggers to run when modules are imported.
* PEAK uses in-package data files, and expects them to be accessible as
regular files. This means that even if reload() worked correctly, it would
break with e.g. putting the package in a zipfile. I do plan to make this
PEP 302 compatible in the near future, by checking for a __loader__
attribute with a 'get_data()' method, and using that instead of direct
filesystem access, if available.
* PEAK uses dynamic and lazy imports extensively, which makes it impossible
to find all its imports using only bytecode analysis. An ability to
specify modules or packages as part of a setup.py is a must.
