### Build script for HolyDragon kernel ###
############################################################

# This is the full build script used to build the official kernel zip.

# Minimum requirements to build:
# Already working build environment :P 
#
# In this script: 
# You will need to change the 'Source path to kernel tree' to match your current path to this source.
# You will need to change the 'Compile Path to out' to match your current path to this source.
# You will also need to edit the '-j32' under 'Start Compile' section and adjust that to match the amount of cores you want to use to build.
# 
# In Makefile: 
# You will need to edit the 'CROSS_COMPILE=' line to match your current path to this source.
# 
# Once those are done, you should be able to execute './build.sh' from terminal and receive a working zip.
