A Revenue Sharing Language agreement generator.
There are threee implementations of the Cascade design for building a multi-step, multi-payee RSL based-agreement:
Cascade Native
Minimal and framework-free, built by Mark Boas.
Cascade Svelte (standalone & civi)
Realtime responsive (ie RSL generates as you type), building on this, compiled in Svelte, with unit tests, by Rich Lott. It compiles to two versions for CiviCRM and for standalone.
