the "egg" part here has nothing to do with eggs. just a vestige of another
and will it work if setuptools was not used in the packages setup.py???
yes, it would work.

"-e" uses setuptools develop mode.
So question one: do I need to use setuptools.setup rather than plain old
the main reason for setuptools is for "install_requires", which is
fundamental to pip dependency resolution.
but in general, it offers more features and it's more maintained than pure
The standard advice is to use setuptools over distutils.
I generally like the pip requirements.txt approach. It's up to the

The Packaging User Guide has a breakdown of install_requires vs
In brief, requirements files are usually for a whole "environment", whereas
install_requires is for a project.
"install_requires" is critical when publishing projects to PyPI.
Even if you're not publishing, install_requires is helpful to safely
attempt an upgrade of your dependencies.
Instead of installing your app from a frozen requirements file, you would
install normally in a clean environment (based on install_requires) and let
any upgrades occur, and then you can re-freeze your requirements.
But if you are doing mostly vcs installs in your requirements file, then
it's true that maintaining install_requires can be somewhat pointless,
although I would still say it's helpful to keep track of each project's
first level abstract dependencies are, even if the install_requires
declarations aren't being used.
