+Subject: [PATCH] capi: add capi feature to enable building with cargo-c
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Disable generating the header since it already exists,
+and more importantly because we cannot run the required custom
+cbindgen extension from cargo-c.
