Time allowing... I managed to take another look at the documentation.

Will have to run additional tests and that may not be possible before
the weekend but in order to make lilypond do what I want in terms of
stem-connection for those (few) instances of cross-staff stems in this
particular score it looks as if I am going to have to define two voices,
right?

From reading the documentation I understand that the purpose of defining
two (or more) voices is to allow users to make lilypond engrave
concurrent notes of different durations (as opposed to chords) but in
this particular case there doesn't seem to be any other way to cause
lilypond to do what I need. 

And by the way, regarding chords... 

One example I looked at when I got started on this used double "<<  >>"
brackets to represent chords whereas the official lilypond documentation
recommends using single "<  >" brackets.

How are they different in terms of lilypond's behaviour?

Reason I am asking is that while I was tidying up my code a bit I tried
to "blindly" replace my double brackets by single brackets at one point
and got some peculiar results in terms of interpreting relative
notation.

Thought it was rather silly anyway to expect a blind search/replace with
no understanding of the implications to do the right thing so I just
backed out my changes and didn't think it worth investigating further.

Anything I should be aware of that I may have missed?

If irrelevant, please ignore.

Thanks,
