Comment:
I don't think each of those commands need to be documented in the help/usage, its already pretty big and there is no point in knowing `dbulk-dump` from a users perspective who is not trying to build tooling around xbps-src.
Same goes for the `show-pkg-var` they do the same thing as `dbulk-dump` but with a "looser" output format.

`remove-destdir` looks like just an alias for `remove`, I don't see the harm in keeping it for compatibility.
