'''
This script is part of the Python argcomplete package (https://github.com/kislyuk/argcomplete).
It is used to check if an EASY-INSTALL-SCRIPT wrapper redirects to a script that contains the string
"PYTHON_ARGCOMPLETE_OK". If you have enabled global completion in argcomplete, the completion hook will run it every
time you press <TAB> in your shell.

Usage:
    python-argcomplete-check-easy-install-script <input executable file>
