Argument format:
‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒

In short:
 foo        Positional argument
 --foo      Option "foo" is True
 --/foo     Option "foo" is False
 --no-foo   Option "foo" is False
 --foo=bar  Option "foo" is "bar"
 -fo        Single letter options "f" and "o" True
 -/ba       Single letter options "b" and "a" False
 -j2        Single letter option "j" with value 2

More verbose:
Command line arguments come in two types: positional and named.
Named arguments start with a "-" and are usually referred to as
"options" in the documentation.  And argument that does not start
with a hyphen, is considered to be a positional argument.

Named and positional arguments can be specified in any order.

Note that the values of some arguments will need quoting in some
form according to rules determined by the shell being used.

If a named argument starts with single "-", then the name is
considered to be a sequence of one letter named arguments
with a boolean True value.  Except if all of the characters
after the first letter are numeric, then these are considered
a numerical value specified with that single letter named
argument.

If a named argument starts with two hyphens, then the characters
after it (until an optional equal sign) are considered to be
the name of a single named argument.  If such a named argument
contains an equal sign, then the characters after the equal sign
are considered the value of that named argument.

If there is no equal sign, then the named argument is supposed
to be a Boolean True value.  Except when there is a slash, or
"no-" after the first hyphen(s), in which case the named argument
is considered to have the boolean False value.
