Where can I find documentation on the "use" directive in Scheme?

I am using Chicken Scheme and I am attempting to understand the meaning of (use abcd) and how it differs from (require-extension abcd). The Chicken website does not seem to have sufficient information to clarify and a web search provided no helpful information. If Anyone would point Me in the direction of such documentation, I would greatly appreciate it. Thanks.

Here's the documentation:

use
[syntax] (use ID ...)

use is just a shorter alias for require-extension.

And just in case:

require-extension
[syntax] (require-extension ID ...)

This is equivalent to (require-library ID ...) but performs an implicit import,
if necessary. Since version 4.4.0, ID may also be an import specification (using
rename, only, except or prefix).

This implementation of require-extension is compliant with SRFI-55 (see the
SRFI-55 document for more information).
