+# sarasacw-omrf
+
+The Rust crate component of **Oh My Rust FFI (SarasaCW OMRF)** — a toolset from Sarasas Chip
+Workshop for authoring Rust libraries that can be distributed and consumed like ordinary CMake
+C/C++ libraries.
+
+This crate provides a small set of facilities for code that is meant to be called from C/C++
+(or any FFI), designed around a distribution-friendly, CMake / pkg-config-style workflow rather
+than in-tree build integration.
+
+## Status
+
+Barely works for the specific workflow of Sarasas Chip Workshop.
+And will be improved by new requirement coming from Sarasas Chip Workshop devlopment.
