Prometheus project is an attempt to create analytic site for developers and users of Sisyphus repository.
It is useful for developers due to ability to more closely interoperate with other developers and users of respective packages. This site is especially valueable to new ALT Linux Team members. It gives answers "who is who", "who does what", "what status is" in interesting field.
Sisyphus users can get full information about a package beforehand. There are handy links (site of origin, ALT Linux specific issues, wiki, etc.).
The project is useful for ALT Linux Ltd. and ALT Linux core team too, as it gives information about Sisyphus development, strong and weak aspects, actively supported and used groups of packages.
Another nice property of the project is posibility to use it together with any other package repository snapshot (not only Sisyphus itself), for local development within a small group or even one's self.
