Args that start with '--' (eg. -v) can also be set in a config file (specified
via --config). Uses configparser module to parse an INI file which allows
multi-line values. Allowed syntax is that for a ConfigParser
with the following options: allow_no_value = False,
inline_comment_prefixes = ("#",) strict = True
empty_lines_in_values = False See
https://docs.python.org/3/library/configparser.html for details.
Note: INI file sections names are still treated as comments. If an
arg is specified in more than one place, then commandline values override
config file values which override defaults.
