Short description on how to build LuneOS with Halium 7.1/9.0:

1. Build Halium as per guide on:

http://docs.halium.org/en/latest/

Basically the parts "Get Halium Source": https://docs.halium.org/en/latest/porting/get-sources.html 
And https://docs.halium.org/en/latest/porting/build-sources.html#initialize

In general LuneOS only needs the system.img (and vendor.img for Halium 9.0 where available) created and archived, so the following commands will suffice:

1. Add your device to the luneos_targets.xml file:
Similar to:
https://github.com/webOS-ports/android/pull/2/commits/4c7c5cbb33da73485cc2c8d249e76bdaf6f75f81

You will want to have a repo with binary blobs (usually from TheMuppets), a repo with your device and a repo with your kernel, so normally 3. In some cases you'll need additional repos, but you'll figure that out during the build. 

2. You can now use the script in xxxx to do a repo sync.

3. You can use the script in yyyy to try to build your device. It will fail at some point, because you will need to disable some of the Android jar/apk bits in the various .mk files.
