How to build

.github/workflows/actions.yml has the formal description on how things are set up and built on Ubuntu 20.04.

• make init sets up minimum submodules (note that it performs git submodule update which will reset those submodules to the specificed commits).
• make builds everything
• make dist collects the target apks.
