Crate is a developer tool to help package up your application as a custom static build of the ruby interpreter plus all dependent binary extensions. All the pure ruby code (the ruby application, the ruby stdlib, etc ) is packed into one or more SQLite databases. The final distributable pieces are a single executable and a few SQLite databases which can be then wrapped up appropriately as an OS X App; a self extracting executable for Windows; a shar archive, rpm or tarball for Unixes.

Convert directories, rpms, python eggs, rubygems, and more to rpms, debs, solaris packages and more. Win at package management without wasting pointless hours debugging bad rpm specs!
