Following are tests for the interop examples in this directory.

Augment Args

$ interop_augment_args
Value of built: false
Value of derived via ArgMatches: false
Value of derived: DerivedArgs {
    derived: false,
}

$ interop_augment_args -b --derived
Value of built: true
Value of derived via ArgMatches: true
Value of derived: DerivedArgs {
    derived: true,
}

$ interop_augment_args -d --built
Value of built: true
Value of derived via ArgMatches: true
Value of derived: DerivedArgs {
    derived: true,
}

$ interop_augment_args --unknown
? failed
error: Found argument '--unknown' which wasn't expected, or isn't valid in this context

	If you tried to supply `--unknown` as a value rather than a flag, use `-- --unknown`
