       Edos-rpmcheck - Check satisfiability of rpm package dependencies


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


       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 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.

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

         gunzip -c | edos-rpmcheck -failures -explain

       where 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 | edos-rpmcheck -explain xemacs=21.4.17-1
