#!/usr/bin/python

​

# Usage (the graphviz package must be installed in your distribution)

#  ./support/scripts/graph-depends [-p package-name] > test.dot

#  dot -Tpdf test.dot -o test.pdf

#

# With no arguments, graph-depends will draw a complete graph of

# dependencies for the current configuration.

# If '-p <package-name>' is specified, graph-depends will draw a graph

# of dependencies for the given package name.

# If '-d <depth>' is specified, graph-depends will limit the depth of

# the dependency graph to 'depth' levels.

#

# Limitations

#

#  * Some packages have dependencies that depend on the Buildroot

#    configuration. For example, many packages have a dependency on

#    openssl if openssl has been enabled. This tool will graph the

#    dependencies as they are with the current Buildroot

#    configuration.
