FESCO approved on 2008-12-17 a proposal to consolidate all the fonts packaging guidelines and associated materials (spec templates[1], macros, etc) in a single helper package.
This package is named fontpackages and available in the current Fedora releases. Its sources are published on fedorahosted in archive and git (git://git.fedorahosted.org/fontpackages.git) formats.
Its content can be discussed on the Fonts SIG mailing list.
While this package has been created by Fedora for Fedora its content should be pretty generic, and apart from the occasional reference to this wiki as documentation source, it should not include any blatant Fedora-ism. Of course it is a bit rpm-oriented so adapting it to a distribution that uses another package format will demand some work.
The Fonts SIG takes loving care of Fedora fonts. Please join this special interest group if you are interested in creating, improving, packaging, or just suggesting a font. Any help will be appreciated.
