+synopsis: "Camlp5 Build scripts (written in OCaml)"
+description:
+"""
+These are build-scripts that are helpful in building Camlp5 and packages based on Camlp5.
+As such, they need to *not* depend on Camlp5.  The command are *not* installed in a
+bin-directory, but in the package-directory, hence invoked via the "ocamlfind package/exe"
+method.
