1# Prints the menu tree of the configuration. Dependencies between symbols can
2# sometimes implicitly alter the menu structure (see kconfig-language.txt), and
3# that's implemented too.
4#
5# Note: See the Kconfig.node_iter() function as well, which provides a simpler
6# interface for walking the menu tree.
7#
8# Usage:
9#
10#   $ make [ARCH=<arch>] scriptconfig SCRIPT=Kconfiglib/examples/print_tree.py
