Define package types for ASF projects (Apache Software Foundation)

[pombredanne]

We should define a package type for ASF projects (Apache Software Foundation)

The spec mentioned originally apache for Apache projects packages. The direction may be to use asf rather than apache.

There have been on-going discussion on the ASF mailing lists on the topic and we need to collect these links for reference and invite the ASF folks to join and help define this (important) package type!
