A simple, common-sense, single-letter command-line parser
flags is a Python flag parsing library for humans, not robots.
Argparse is complicated. Plac remedies most of its issues. However, sometimes you just need a really simple POSIX-style flag parser. You can use getopt, but it makes you write all the help screens yourself, which can easily go out-of-sync with the program source. flags aims at filling this void by providing a simple, practical API that’s truly easy to use and doesn’t suck.
Since README examples always go out of sync with the source, included at examples/grep.py is flags parser for POSIX grep’s arguments.
