The web pages include prev and next links, so to get those right we
have to make the tune filenames distinct from the main booke names.
So fall back to taking the easy way, and just prefix all tune names with
@ or _.
Sort alternate .abc in subdir 'Compact' under the booke dir. Use that as
the graphic for A5 output, assuming it will be vertically more compact.
Use Bear Dance as an example, as it has commentary that currently
overflows an A5 landscape page.
For the moment, transposed Bookes don't transpose and so don't use Compact.
This is done by
a) reducing the page margins
b) compressing the heading and removing all but Notes: fields.
The latter produced vertically smaller tune PDFs that will scale wider.
In the process, modify abctitle.py to extract the first of any header field, and
move formatting for a single tune into a .fmt file.
Also switch to Times New Roman for the main text. The music is set
with Postscript Times, so this is the easy approach to better typographic
consistency.
Add a list of tune first lines to the Booke. First, a small Python script to
filter a .abc file and spit out just enough to give a graphic of the first line
without the title. Then generate these graphics and generate a new section in the Booke
with a longtable of tune name and the first line graphic.
