rpmgraph uses PACKAGE_FILE arguments
to generate a package dependency graph. Each
PACKAGE_FILE argument is read and
added to an rpm transaction 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 dependencies as a relation. That means that the
parent of a given package is the packages 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.
