The ScrollKeeper project aims directly to meet this need. It provides a simple set of script hooks that can be used by package install and uninstall productions to register and unregister their documentation.

ScrollKeeper uses the Open Metadata Format. This is a standard for indexing open-source documentation analogous to a library card-catalog system. The idea is to support rich search facilities that use the card-catalog metadata as well as the source text of the documentation itself.
