Orthrus

Orthrus is a work-in-progress modding toolkit that aims to support a wide array of game file formats, to allow for blazing fast interoperability across systems and game engines. Project goals are minimizing dependencies and allocations (where possible), as well as running as fast as possible.

For more about the structure of the Orthrus project, see the Architecture page.
