Re: Overriding bar-line behaviour

[Matthias Hüsken]

Ok, I give up for tonight - obviously, before writing my last mail I tested 
while having the new barline definitions in scm/output-lib.scm (instead of 
reverting that file).

Which means I cannot get things to work without modifying scm/output-lib.scm. 
Any ideas how to put this into a .ly file are most welcome...
