Testing distributionsΒΆ

You can use distil to test distributions. This is primarily intended for trying out potential dependencies and exercises distlib‘s logic for distinguishing between dependencies needed for setup, testing and post-installation:

$ distil test jinja2

Dependencies of the distribution under test are automatically downloaded and built:

$ distil -e e2 test argproc

The following packages will be downloaded and built:
    nose (1.2.1) [for argproc]

OK

Note that the dependencies are not installed - they are downloaded and built purely for the purposes of testing, and discarded afterwards.
