My previous attempt appeared to work, but didn't actually centre graphics
if the graphic was less than page width.
Revert, and instead add a \vfill before the tune to leave more blank space
between multiples tunes on a page, It's more obvious then which tune the
change belongs to. Not idea, but the best I can do for now.
I was using \begin{center}..\end{center} to centre the tune graphic,
followed by the change notice, if any.
But this leaves a paragraph gap after the center section and hence a gap
between tune graphic and change notice.
Change to use figures to position the graphic, include the change notice
as a caption, and use {\centering} around the image to centre just the image.
Put a big title in English Towne, the official Havoc font.
Add a title for each volume, and also print the subtitle on the cover.
Add the buzzard, too. On A5, we now need to split the title page across two
physical pages. This looks OK to me.
Change all change notes to reference the filename of the tune to change to.
Modify web and document generators to pull the change note out of the abc
and generate an appropiate bit of content. This is now, in both cases,
a hyperlink.
In the process, remove the tune-specific .tex facility. It wasn't being
used.
I could really do with a proper templating system, and using some sort
of templating in the LaTeX generation.
