Describe your use case

Since I'm using clap to create an interactive cl program, I'd like to skip whole "USAGE: " section since it shows very few useful information and takes up quite a lot of screen-space:

USAGE:
    myapp [SUBCOMMAND]

For more information try --help

Describe the solution you'd like

It would be great to customize the error message. For example, select which parts should be shown (error, usage, additional information).

Alternatives, if applicable

For now just cutting off everything after "USAGE:" kinda works but it's not really pretty.

With some mentoring I'd maybe try to implement it myself if this is considered a good addition.
