Could we add something like the following? It was not at all obvious
to me how to do this until I read package-get.el.
Finding the right packages
--------------------------
If you want to find out which package contains the functionality you
are looking for, use M-x package-get-package-provider, and give it a
symbol that is likely to be in that package. eg, if some code you
want to use has a (require 'thingatpt) in it, try doing
M-x package-get-package-provider RET thingatpt , which will return
something like: (fsf-compat "1.06").
