## A script to compile Hyperion inside a docker container
## Requires installed Docker: https://www.docker.com/
## Without arguments it will compile Hyperion for Debian Buster (x86_64) and uses Hyperion code from GitHub repository.
## Supports Raspberry Pi (armv6l, armv7l) cross compilation (Debian Stretch/Buster) and native compilation (Raspbian Stretch/Buster)
##
## Homepage: https://www.hyperion-project.org
## Forum: https://forum.hyperion-project.org
