# ***** ***** ***** ..How to use this script… ***** ***** ***** #
#
# For those who want to build this kernel using this script…
#
# 1. Properly locate toolchain (Line# 44)
# 2. Set 'KERNEL_VARIANT' (Line# 40).
# 3. To build all the supported variants, set 'KERNEL_VARIANT' to "all"
# 4. Open Terminal, ‘cd’ to the Kernel ‘root’ folder and run ‘. build_boeffla.sh’
# 5. The output (anykernel zip) file will be generated in the ‘release_boeffla’ folder
# 6. Enjoy your new Kernel
#
# ***** ***** *Variables to be configured manually* ***** ***** #
