Following example are the same:

wampy -s cbor
wampy -s=cbor

wampy call uri --argsList 1 2 3 ==> [1, 2, 3]
wampy call uri --args 1 2 3     ==> [1, 2, 3]
wampy call uri -a 1 2 3         ==> [1, 2, 3]
wampy call uri -a=1 2 3         ==> [1, 2, 3]
wampy call uri -a 1 -a 2 -a 3   ==> [1, 2, 3]
wampy call uri -a=1 -a=2 -a=3   ==> [1, 2, 3]

Wampy also supports reading arguments from environment variables prefixed with "WAMPY_"
For example, serializer may be read from ENV like this:
WAMPY_SERIALIZER=cbor wampy call ...

Program arguments are defined in this order of precedence:
1. Command line args
2. Env vars
3. Config file/objects
4. Configured defaults

To get information about command options just type: wampy <command> -h`
    );

export default argv;
