# Configuration targets
#
# These targets depend on the kconfig-frontends packages.  To use these, you
# must first download and install the kconfig-frontends package from this
# location: http://ymorin.is-a-geek.org/projects/kconfig-frontends.  See
# misc\tools\README.txt for additional information.

# export
#
# The export target will package the NuttX libraries and header files into
# an exportable package.  Caveats: (1) These needs some extension for the KERNEL
# build; it needs to receive USERLIBS and create a libuser.a). (2) The logic
# in tools\mkexport.sh only supports GCC and, for example, explicitly assumes
# that the archiver is 'ar'

# General housekeeping targets:  dependencies, cleaning, etc.
#
# depend:    Create both PASS1 and PASS2 dependencies
# clean:     Removes derived object files, archives, executables, and
#            temporary files, but retains the configuration and context
#            files and directories.
# distclean: Does 'clean' then also removes all configuration and context
#            files.  This essentially restores the directory structure
#            to its original, unconfigured stated.

# 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_clean:     Perform the clean operation only in the user application
#                 directory
# apps_distclean: Perform the distclean operation only in the user application
#                 directory.  Note that the apps\.config file (inf any) is
#                 preserved so that this is not a "full" distclean but more of a
#                 configuration "reset." (There willnot be an apps\.config
#                 file if the configuration was generated via make menuconfig).
