Opam_0install
module Dir_context : sig ... end
A context that reads opam files directly from an opam-repository checkout. It does not use a switch, and therefore does not pick up any pins the user has set. It also does not get any opam variables from the environment - instead, the caller must provide them explicitly.
module Model : sig ... end
This module maps between the opam and 0install concepts. Roughly:
module S : sig ... end
module Solver : sig ... end
module Switch_context : sig ... end
