# This script is designed to process resource files that are necessary for a single component. It converts each
# resource file into a binary object and then stores that into an array in a .c file. The .c file can then be compiled
# with and linked into an application image.
#
# Once all resources files have been converted it will generate a header file that references each of them.
#
# usage:
#	genresources.bash <RECIPE_DIR> <SCRIPTS_DIR> <RESOURCE_FILE> <PROJECT_DIR> <TARGET_DIR> <FILESYSTEM|MEM> [s]
