Highlights

Arg::num_args(range)

Clap has had several ways for controlling how many values will be captured without always being clear on how they interacted, including

• Arg::multiple_values(true)
• Arg::number_of_values(4)
• Arg::min_values(2)
• Arg::max_values(20)
• Arg::takes_value(true)

These have now all been collapsed into Arg::num_args which accepts both single values and ranges of values. num_args controls how many raw arguments
