# 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...
