Dependencies should be listed in setup.py

[jpic]

I thought I'd get away with this command like for every python module (which I want the dev version or which hasn't been submitted to PyPi yet):

pip install -e git+git://github.com/jflesch/paperwork.git#egg=paperwork

While this did clone the repo and run setup.py fine, it didn't install the dependencies.

I think it is a mistake to rely on packages provided by insert your debian-based distro name here. Instead, it would be better to rely on PyPi, the official Python package index, like all python apps. Not only because it ensures fresher dependencies and dependency version locking, but also because it is cross platform, and supports virtualenv.

To do so, you can use the install_requires kwarg of the setup() function.

Hm, it seems that there are some dependencies that I can't add to setup.py. For instance, gobject-introspection-thingies (like Gtk, Poppler) are not available on pypi.
However, I can still add the other ones.

I've removed the dependency list from the README.

It is now in the setup.py.

However, as I said, there are dependencies that can't be checked by setuptools. So I added some custom code in setup.py to look for those dependencies. If some of them are not available, it will tell the user what command to run to install them (on Fedora, Ubuntu, Debian and Gentoo for now).

I don't think I can do any better.
