# Manual opt parsing example
#
# Features:
# - supports short and long flags (ie: -v|--verbose)
# - supports short and long key/value options (ie: -f <file> | --filename <file>)
# - supports short and long key/value options with equals assignment (ie: -f=<file> | --filename=<file>)
# - does NOT support short option chaining (ie: -vh)
# - everything after -- is positional even if it looks like an option (ie: -f)
# - once we hit an arg that isn't an option flag, everything after that is considered positional
