A package dependency resolver based on a SAT solver. This was
originally written for the 0install package manager, but is now
generic and is also used as a solver backend for opam. The SAT solver
is based on MiniSat and the application to package management is based
on OPIUM (Optimal Package Install/Uninstall Manager). 0install-solver
uses a (novel?) strategy to find the optimal solution extremely
quickly (even for a SAT-based solver).
