# CONFIGURED_APPS is the list of all configured built-in directories/built

# appears in this directory as .config)

# only for cleaning. namedapp must always be the first in the list. This
# list can be extended by the .config file as well.

# There are two different mechanisms for obtaining the list of configured
# directories:
#
# (1) In the legacy method, these paths are all provided in the appconfig
# file that is copied to the top-level apps/ directory as .config
# (2) With the development of the NuttX configuration tool, however, the
# selected applications are now enabled by the configuration tool.
# The apps/.config file is no longer used. Instead, the set of
# configured build directories can be found by including a Make.defs
# file contained in each of the apps/subdirectories.
#
# When the NuttX configuration tools executes, it will always define the
# configure CONFIG_NUTTX_NEWCONFIG to select between these two cases. Then
# legacy appconfig files will still work but newly configuration files will
# also work. Eventually the CONFIG_NUTTX_NEWCONFIG option will be phased
# out.
