A documentation string in guile?

[9]

Hi, everyone.

I've looked over the guile info pages and it told me that guile might have
something like a `documentation string'. It seems that I could provide
a documentation string in my procedure just like the LISP language.

But I don't know how to provide a documentation string when I define
scheme procedures. I tried in the same way what I do when I use LISP,
but I failed.

My questions are:

(1) Does guile have a documentation string feature? I suspect that scheme
    doesn't have a documentation string.

(2) If so, how can I provide a documentation string in my procedures?
