+This folder contains an experimental C wrapper for using parts of the Nimbus

+
+To build the wrappers and the example programs, run from the top level directory:
+
+```bash
+make wrappers
+```
+
+Now you can run the example programs:
+
+```bash
+build/C_wrapper_example
+build/go_wrapper_example
+```
+
+To build statically linked versions:
+
+```bash
+make wrappers-static
