RPMGRAPH(8)							   Red Hat Linux						       RPMGRAPH(8)

NAME

       rpmgraph - Display RPM Package Dependency Graph

SYNOPSIS

       rpmgraph PACKAGE_FILE ...

DESCRIPTION

       rpmgraph  uses PACKAGE_FILE arguments to generate a package dependency graph. Each PACKAGE_FILE argument is read and added to an rpm trans-
       action set. The elements of the transaction set are partially ordered using a topological sort. The partially  ordered  elements  are  then
       printed to standard output.

       Nodes  in  the  dependency  graph  are  package names, and edges in the directed graph point to the parent of each node. The parent node is
       defined as the last predecessor of a package when partially ordered using the package depndencies as a relation. That means that the parent
       of a given package is the package's last prerequisite.

       The  output  is	in  dot(1)  directed graph format, and can be displayed or printed using the dotty graph editor from the graphviz package.
       There are no rpmgraph specific options, only common rpm options.  See the rpmgraph usage message for what is currently implemented.
