Well there are 2 ways, either "action='append'" or "nargs='+'". They behave
similarly, but 'append' requires repetition of the arg:
--mux-yaml foo --mux-yaml bar --mux-yaml baz
while 'nargs' assumes everything that is not argument belongs to it:
--mux-yaml foo bar baz
I personally prefer the later even though sometimes it might be confusing (and
for example when you want to specify `-` in filename you have to use
`--mux-yaml=-foo` (and I'm not aware of a way to specify multiple of items
starting with `-`). Anyway currently we were discussing the possibility of
unifying these (as both are used in Avocado). We planned to chose the 'nargs'
but let's discuss this on our next planning meeting...
