USAGE: mnamer [preferences] [directives] target [targets ...]
POSITIONAL:
foo1
foo2
foo3
PARAMETERS:
The following flags can be used to customize mnamer's behaviour. Their long
forms may also be set in a '.mnamer-v2.json' config file, in which case cli
arguments will take precedence.
bar1
bar2
bar3
DIRECTIVES:
Directives are one-off arguments that are used to perform secondary tasks
like overriding media detection. They can't be used in '.mnamer-v2.json'.
baz1
baz2
baz3
