Utilities/Sphinx: Add 'cref' role
Add a role that can be used to create local links (a la `LINK`_
), but that also applies literal style. This is particularly useful for referring to subcommands within the command's documentation in a style that is consistent with :command:`BAR <foo(BAR)>`
but is much less verbose.
Although this is intended for subcommands, it works with any local reference.
