Re: OLL not working with lilypond 2.22

[Andrew Bernard]

Hi Valentin,

I took over the OLL project from Urs, and have been intending to move 
the git repo to a new more unified and refactored structure. I have not 
been able to complete this yet, and due to a major and stupid bungle on 
my part I accidentally deleted the new OLL website I made, and the 
Discourse server, and my OLL repo work (I had to delete a hosted server 
and the OLL stuff slipped my mind!)

The point being the current git repo is idle and pretty sure Urs is not 
taking pull requests or working on it.

Well this should be the stimulus for me to get back to work on it pronto.

Apologies for the inconvenience.

Andrew
