# Application housekeeping targets.  The APPDIR variable refers to the user
# application directory.  A sample apps\ directory is included with NuttX,
# however, this is not treated as part of NuttX and may be replaced with a
# different application directory.  For the most part, the application
# directory is treated like any other build directory in this script.  However,
# as a convenience, the following targets are included to support housekeeping
# functions in the user application directory from the NuttX build directory.
#
# apps_preconfig: Prepare applications to be configured
# apps_clean:     Perform the clean operation only in the user application
#                 directory
# apps_distclean: Perform the distclean operation only in the user application
#                 directory.
