I use a script under virtualenv, that requires bzrlib package which is not available in my virtualenv but is included in my system python packages: /usr/lib/python2.7/dist-packages/bzrlib/
If I want to use it, one option is to extend sys.path, but I would have to include the parent folder /usr/lib/python2.7/dist-packages/
which contains many other packages, that I don't want to make available. Is there any easy way to include just bzrlib
package?
