## Sample makefile to show how to include user apps.
##
## This makefile has access to following project variables:
##
##	DEL_TOOL_DIR -> Digi Embedded Linux path.
##	DEL_PROJ_DIR -> Project path.
##	DEL_PLATFORM -> Target platform.
##	DEL_TFTP_DIR -> TFTPBOOT path.
##	DEL_NFS_DIR  -> Rootfs nfs-exported path.
##
## These variables are configured in topdir Makefile.
##
## Though you can use DEL_NFS_DIR to install your application to the
## exported rootfs directly, the recommended way is to install it in
## the project rootfs (see ROOTFS_DIR below). Doing this way, your
## application will be check for library dependences and then installed
## both in DEL_NFS_DIR and in rootfs images.
