+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").
