    <p>I had my fair chance of getting through the python management of modules, and every time is a challenge: packaging is not what people do every day, and it becomes a burden to learn, and a burden to remember, even when you actually do it, since this happens normally once.</p> <p>I would like to collect here the definitive overview of how import, package management and distribution works in python, so that this question becomes the definitive explanation for all the magic that happens under the hood. Although I understand the broad level of the question, these things are so intertwined that any focused answer will not solve the main problem: understand how all works, what is outdated, what is current, what are just alternatives for the same task, what are the quirks.</p> <p>The list of keywords to refer to is the following, but this is just a sample out of the bunch. There's a lot more and you are welcome to add additional details. </p> <ul> <li>PyPI</li> <li>setuptools / Distribute</li> <li>distutils</li> <li>eggs</li> <li>egg-link</li> <li>pip</li> <li>zipimport</li> <li>site.py </li> <li>site-packages</li> <li>.pth files</li> <li>virtualenv</li> <li>handling of compiled modules in eggs (with and without installation via easy_install)</li> <li>use of get_data()</li> <li>pypm</li> <li><a href="http://cournape.github.com/Bento/">bento</a></li> <li><a href="http://www.python.org/dev/peps/pep-0376/">PEP 376</a></li> <li>the cheese shop</li> <li>eggsecutable</li> </ul> <p>Linking to other answers is probably a good idea. As I said, this question is for the high-level overview.</p>

    3. CO@Stefano Borini: I doubt there is a "short" story. Can you define what this "short" story would look like? You've listed 13 things which are not very closely related. What are you expecting? Can provide some kind of outline or hint as to what a "short" story might look like for all these topics?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
