NAME

       Edos-pscheck - Check satisfiability of pkgsrc package dependencies

SYNOPSIS

       edos-pscheck [option] ... pkg-summary-file

DESCRIPTION

       edos-pscheck  reads  package descriptions from a file in the pkg_summary format of NetBSD.  We say that a package is identified by the pair
       consisting of the package name and of the package version.

       A package (called goal) is called installable with respect to a set of packages if there exists a subset of the packages that
	- contains at most one version for each package name
	- contains the goal package (in any version, or a specific version)
	- all packages of the subset have their dependencies and conflicts satisfied in this subset.

       Edos-psmcheck checks whether every package in the set is installable with respect to the input set of packages. Specific  versions  can	be
       specified  by following the package name with the sign '=' and the version of the package (for instance, 'xemacs21=21.4.17-1'). If no pack-
       age name is given as argument then all packages of the input set are checked for satisfiability.

       The constraint solving algorithm is complete, that is it finds a solution whenever there exists one, even for multiple  disjunctive  depen-
       dencies	and  deep  package  conflicts. This problem is computationally infeasible in theory (that is, NP-complete), but can in practice be
       solved very efficiently.
