# Script to compress and build additional spiffs file system for DWC
#
# This script requires the following tools:
# - mkspiffs from https://github.com/igrr/mkspiffs/releases
# - yui-compressor from https://yui.github.io/yuicompressor
# Make sure both tools are accessible via your PATH environment variable!
