Comments from notes.txt:

Different arg types:
* -name <mandatory value>
* -name <no value, it's a switch>

Both of these types in addition have a cardinality. For instance:
-name -name -name
-name value1 -name value2 -name value3

Possible Tests
-------------------

    ./foo -ab -cd - - -
    ./foo -ab -cd - input1 input

    ./foo - -help


    // -switch has upper limit of 2
    ./foo -switch -switch -switch

    // -switch has upper limit of 1

    // -switch has lower limit of 1
