Flag: plugins

[steveklabnik]

This issue is part of #125

--plugins:

Using this flag looks like this:

$ rustdoc src/lib.rs --plugins foo bar

For more, see the chapter on plugins.

See also: --plugin-path.

Should we keep this flag or not?

[steveklabnik]

I'd like to see plugins removed from current rustdoc entirely, I don't think we want to support this in new rustdoc, exactly.

Instead of writing a rustdoc plugin, you'd write something using rustdoc as a library, and do that.

We talked about this at the tools team meeting today and the intention is to remove this flag. We're going to remove plugins.

rust-lang/rust#44136 is the issue tracking the deprecation; it may or may not be removed, but it means we don't need to support it.
