Including git version in setup.py files. (Requires at least _one_ tag in the repo) Normally used to make things like, "python setup.py sdist" give you a predictable name for files. Normally used with tags on the repo like 0.1 or 2.3.0 You should add RELEASE-VERSION to MANIFEST.in so that end users of the tarball can use this too.
include RELEASE-VERSION
include version.py

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

    • Who is going to use it?
