So:

- - Section describing package/plugin versions, needs to be enough
flexibility to specify either a revision or tip of a bzr branch or a
published download tarball.
- - Sections for each platform describing the list of packages/plugins
used and any package/plugin version overrides needed for that platform.
- - Destination directory information should be optional and derived from
the plugin/package name.

We could have a shared library which reads this file and provides
functions for fetching and extracting files. Where would be a good home
for a library such as this?

Ciao,
Gordon
