In preparing this package I've found that the python-build-system (not
sure about the others) defines the environment variable HOME as
"/homeless-shelter". However, that directory does not exist in the
build chroot. This is a problem for cython, because it wants to access
$HOME/.cython. Wouldn't it be better to point HOME to an existing
directory (created in the chroot) with suitable permissions?

I'm a little bit unsure about the name of the package. I've not
prefixed it with "python[2]-" as the program extends the Python
language and can work with both (2 and 3) Python version series.
However, the package installs files in
".../lib/python${version}/site-packages/...". The naming is in-line
with Debian naming.


Regards,
Fede
