+libmd - Message Digest functions from BSD systems
+
+This library provides message digest functions found on BSD systems either
+on their libc or libmd libraries and lacking on others like GNU systems,
+thus making it easier to port projects with strong BSD origins, without
+needing to embed the same code over and over again on each project.
