python3-gflags is:

GFlags defines a distributed command line system, replacing systems like getopt(), optparse and manual argument processing. Rather than an application having to define all flags in or near main(), each Python module defines flags that are useful to it. When one Python module imports another, it gains access to the other’s flags.

It includes the ability to define flag types (boolean, float, integer, list), autogeneration of help (in both human and machine readable format) and reading arguments from a file. It also includes the ability to automatically generate man pages from the help flags.

This package provides the Python 3.x module.
