A self-updating wrapper script for the Certbot ACME client. When run, updates
to both this script and certbot will be downloaded and installed. After
ensuring you have the latest versions installed, certbot will be invoked with
all arguments you have provided.
Help for certbot itself cannot be provided until it is installed.
--debug attempt experimental installation
-h, --help print this help
-n, --non-interactive, --noninteractive run without asking for user input
--no-self-upgrade do not download updates
--os-packages-only install OS dependencies and exit
-v, --verbose provide more output
-q, --quiet provide only update/error output;
implies --non-interactive
All arguments are accepted and forwarded to the Certbot client when run."

# `su`. Auto-detection can be overridden by explicitly setting the
# environment variable LE_AUTO_SUDO to 'sudo', 'sudo_su' or '' as used below.

# 'echo' 'It'"'"'s only 1$!'

"""A small script that can act as a trust root for installing pip 8
Embed this in your project, and your VCS checkout is all you have to trust. In
a post-peep era, this lets you claw your way to a hash-checking version of pip,
with which you can install the rest of your dependencies safely. All it assumes
is Python 2.6 or better and *some* version of pip already installed. If
anything goes wrong, it will exit with a non-zero status code.
