# What does this do.. and why?
# (and why is it so complicated?)
#
# What this does
#
# 1. Sets some vars and asks some questions
# 2. Installs everything into a single place
# (inculding deps like node.js, with the correct version)
# 3. Depending on OS, creates a user for the service
# 4. Depending on OS, register with system launcher
#
# Why
#
# So that you can get a fully configured, running product,
# with zero manual configuration in a matter of seconds -
# and have an uninstall that's just as easy.
#
# Why so complicated?
#
# To support nuance differences between various versions of
# Linux, macOS, and Android, including whether it's being
# installed with user privileges, as root, wit a system user
# system daemon launcher, etc. Also, this is designed to be
# reusable with many apps and services, so it's very variabled...
