/* Topkg is a packager for distributing OCaml software. This derivation
provides facilities to describe derivations for OCaml libraries
using topkg.
The `buildPhase` and `installPhase` attributes can be reused directly
in many cases. When more fine-grained control on how to run the topkg
build system is required, the attribute `run` can be used.
