is there C-h help for a "require" feature?

[Robert P. J. Day]

  looking at someone else's elisp load file, and for the line
(require 'cl), is there any C-h help for "cl"?  given that it's
not a function or variable, is there another C-h key sequence
that would give help for that, perhaps from embedded documentation
in the corresponding file?

`(require 'cl)' makes sure cl.el (Common Lisp-like functions) are
loaded.  `cl' is just a symbol, and if it's not in the `features' list
then the corresponding file is loaded.  Are you looking for some
method of attaching per-file documentation?  Sounds like a slick idea,
but not supported by the current `require'/`provide' mechanism
(AFAIK).

that part i had pretty much figured out.

that's what i was asking about, kind of like the DOCSTRING part of
a "defvar".  ah well, it was a shot in the dark.

There's `M-x finder-commentary'.

You can take a look at (cdr (assoc "cl" load-library)) to see
what functions/variables are defined.
