NAME
       Edos-rpmcheck - Check satisfiability of rpm package dependenā€
       cies


SYNOPSIS
       edos-rpmcheck [option] ... [package] ...


DESCRIPTION
       edos-rpmcheck reads from standard input a set of rpm  package
       descriptions.  Packages  may appear with multiple versions in
       this set. For instance, an uncompressed hdlist.cz is suitable
       as input.

       We  say  that a package is identified in this set 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-rpmcheck checks whether every package given as  argument
       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 package 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 dependencies and  deep  package  conflicts.  This
       problem is computationally infeasible in theory (that is, NP-
       complete), but can in practice be solved very efficiently.

              Only show successes

       -base file
              Specifiy an additional file  providing  packages  that

EXAMPLE
       Check  which  packages  in  a particular distribution are not
       installable and why:

         gunzip -c hdlist.cz | edos-rpmcheck -failures -explain

       where hdlist.cz is the file pertaining to that distribution.

       Check whether version 21.4.17-1 of the  xemacs21  package  is
       installable in a distribution described by the file Packages:

         gunzip    -c    hdlist.cz    |    edos-rpmcheck    -explain
       xemacs=21.4.17-1
