Enigma2 Bouquet Import

May be me being daft but how do you use the new Enigma2 Bouquet import feature in 4.2?

Is it documented anywhere?

From the release notes:

Import enigma2 bouquets automatically using file:// and http[s]:// URLs.

If importing from file:// what format are the bouquet files expected to be in?

I have my settings from enigma2 backed up (*.tv files and lamedb) but no idea how to import them?

Forgive me for answering a question with question but how are you getting the 4.2 source?

I have libreelec installed on my STB and they have it in their repo

In case anyone else is wondering you just need to create the individual bouquets and point them directly at the .tv files from the e2 bouquets.

Works well with LraiZer's AutoBouquets for Sat/Cable for people in the UK.
