# This script generates the Rust source from the C <shmem.h> file.  It
# pulls out constants, globals, enums etc. that need to be replicated
# as part of the Rust-based API (./shmemlib).  Our shmem interface
# (./shmem) then hides the nasty details of the generated bindings and
# presents them in a Rust-safe manner to the end-programmer.
