[Commotion-dev] Commotion packages outside Commotion firmware

[Dan Staples]

Hi Geneviève,

I just talked with our lead developer, and we are planning on pulling
out commotion_helpers into a separate OpenWRT package in the next few
weeks, so that you would be able to install Commotion-splash without any
unnecessary dependences. But for now, I would say just include the
commotion_helpers.lua file in /usr/lib/lua.
