# support is disabled. NOTE that drivers, in general, depends on file
# descriptor support but is always built because there are other components
# in the drivers directory that are needed even if file descriptors are not
# supported.
# CONTEXTDIRS include directories that have special, one-time pre-build
# requirements. Normally this includes things like auto-generation of
# configuration specific files or creation of configurable symbolic links
# USERDIRS - When NuttX is build is a monolithic kernel, this provides the
# list of directories that must be built
# OTHERDIRS - These are directories that are not built but probably should
# be cleaned to prevent garbage from collecting in them when changing
# configurations.
