It's an odd way of doing things, effectively having to enclose a \book with
a \book. Not only that, but it doesn't work correctly in terms of naming the
output files.
If I compile:
\book { \GuitarBook }
\book { \ConcertBook }
\book { \TrumpetBook }
\book { \AltoBook }
I get the correct information in the output files, but the filenames are...
TestTag (alto).pdf
TestTag (alto)-1.pdf
TestTag (alto)-2.pdf
TestTag (alto)-3.pdf
...although the definition of GuitarBook includes '\bookOutputName "TestTag
(gtr)"', and so on for the other parts.
If I switch the order around...
\book { \AltoBook }
\book { \GuitarBook }
\book { \ConcertBook }
\book { \TrumpetBook }
The names all include "(alto)", as before, but the contents are
TestTag (alto).pdf - Alto Part
TestTag (alto)-1.pdf - Guitar Part
TestTag (alto)-2.pdf - Concert Part
TestTag (alto)-3.pdf - Trumpet Part
It looks as though \bookOutputName is treated as a global variable, even
though it's defined inside a \book {} which is itself defined within a
variable's assignment statement.
