* +--depth N+, +-d N+, to limit the dependency depth to +N+ levels. The
default, +0+, means no limit.
+* +--stop-on PKG+, +-s PKG+, to stop the graph on the package +PKG+.
+ +PKG+ can be an actual package name, a glob, or the keyword 'virtual'
+ (to stop on virtual packages). The package is still present on the
+ graph, but its dependencies are not.
+
+* +--exclude PKG+, +-x PKG+, like +--stop-on+, but also omits +PKG+ from
+ the graph.
+
* +--transitive+, +--no-transitive+, to draw (or not) the transitive
dependencies. The default is to not draw transitive dependencies.
