We have discussed the use of the clap crate on Zulip¹. At this point we have come to the consensus that we are happy to explore the use of clap in the radicle-cli crate. The expectations for it to be fully accepted as the replacement for CLI arg parsing are the following:

• It must at least be similar, if not an improvement, on top of the existing output. The usage examples are definitely somewhere where we need to spend the most time when implementing it – as the default style was quite different.
• A benchmark of the compile times is taken and compared, and we accept that there isn't too much of an overhead when introducing clap.
