Merge lp://staging/~ted/snapcraft/python-pip into lp://staging/~snappy-dev/snapcraft/core

Are you rendering the py3 and py2 examples useless here by removing handle_source options?

I also bring this question up often enough (internally at least); with this implemented in python instead of python-project, what is the reason for python-project (or any .*-project at all?)

hey this looks good, it just seems that py2 took a different path than py3.

This also removes the use case (which is rather neat) that the py2-project and py3-project examples bring in.

python2 and python3 for pip is fine fwiw

So, some slight modifications. Switched from --root to --target as it seems in recursive cases that causes "bad things to happen" in that it appends twice. But target doesn't have that problem. Also moved the PYTHONPATH to the standard snapcraft environment handling. Now I can build a Nova snap:

Still would like to figure out if we can fix the command line support in setuptools to not put in the full path in a shebang, but that's not really a pip issue.

I was confused, I didn't see your comments in the diff... handled now.
Thanks!

This is what I see when doing

cd examples/webcam-webui
../../bin/snapcraft

...
Building config

error: bad install directory or PYTHONPATH

You are attempting to install a package to a directory that is not
on PYTHONPATH and which Python does not read ".pth" files from. The
installation directory you specified (via --install-dir, --prefix, or
the distutils default setting) was:

    /home/sergiusens/source/launchpad.net/snapcraft/examples/webcam-webui/parts/config/install/usr/lib/python3/dist-packages/

and your PYTHONPATH environment variable currently contains:

    '/home/sergiusens/source/launchpad.net/snapcraft/examples/webcam-webui/parts/python3/install/usr/lib/python3/dist-packages'

Here are some of your options for correcting the problem:

* You can choose a different installation directory, i.e., one that is
  on PYTHONPATH or supports .pth files

* You can add the installation directory to the PYTHONPATH environment
  variable. (It must then also be on PYTHONPATH whenever you run
  Python and want to use the package(s) you are installing.)

* You can set up the installation directory to support ".pth" files by
  using one of the approaches described here:

  https://pythonhosted.org/setuptools/easy_install.html#custom-installation-locations

Please make the appropriate changes for your system and try again.
Failed doing build for config!

Nice

Thanks! This was a tough one!
