.SH NAME

rpmgraph \- Display RPM Package Dependency Graph

.SH SYNOPSIS

.PP

\fBrpmgraph\fR \fB\fIPACKAGE_FILE\fB\fR\fI ...\fR

.SH "DESCRIPTION"

.PP

\fBrpmgraph\fR uses \fIPACKAGE_FILE\fR arguments

to generate a package dependency graph. Each

\fIPACKAGE_FILE\fR 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.

.PP

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 package's last prerequisite.

.PP

The output is in \fBdot\fR(1) directed graph format,

and can be displayed or printed using the \fBdotty\fR

graph editor from the \fBgraphviz\fR package.

There are no \fBrpmgraph\fR specific options, only common \fBrpm\fR options.

See the \fBrpmgraph\fR usage message for what is currently implemented.
