# @goal: satisfy mel's curiousity
# @practice: never do anything for just one reason
# @advice: when stuck, do something functionally/tactically frivelous with long term strategic benefit.

# @todo double check input sanitization#
# @todo (better)feature flags mebbe?
# @todo load functions.sh if it exists on the system
# @todo loop user input bits until valid/exit path found
# @todo command line params for config bits
# @todo split actual install into install.sh, obviously
# @todo scan docs for missing/broken links, combine with archive.is replacement?
