Agreed on both counts.  The API I'm providing can be combined with the
manual generation to do this, and it will use the manual sections to get
the first keyword seeds.  I don't want the manual to be the primary
source of keywords, that's all.

There are many many packages and functions not covered in the manual
that are nevertheless used and useful.  They can and should have
keywords.  So the docstring should be the primary source of keywords,
and looking up the function with C-h f should be the primary way to
cross-reference functions by keyword.

The goal of this API is not to index Emacs' internal functions'
keywords.  It will cover everything that `mapatoms' returns; I'm
considering symbols in addition to functions but I want to get functions
working first.
