I'm just having a first bash at this, and I'm doing it using OpenOffice
Write to produce what I want texinfo to produce, so I can concentrate
on the content, rather than getting the texinfo source correct. I did
start trying with the texinfo source in emacs but my brain started
overheating so I decided to do this in two stages.
This is very much a draft, some bits of text are placeholders [bits
like this in square brackets], where I have put a header in and need
something to remind me why it was there.
I realize there are some bits that could be removed and replaced by
references to what's in the current CG, but the intention is to give
the reader a slightly gentler lead-in to the document before beating
them over the with the git, compiling the source, using texinfo mark-up
language in emacs etc.
Carl, Graham, anyone else interested, please let me know if you think
this is worth me working on further when I next get some more time for
Lilypond stuff next weekend.
