Spirit API is a cross-loader API I use for my mods that abstracts the Neoforge and Fabric energy, fluid, and item APIs and adds a new similar Soul API.
Like many small mod libraries, this one is mostly designed to support my own mods and is not trying to be flexible, comprehensive, or stable.
This is a library, and will not do anything on its own.
