i'm generating 5 pdf files (score & parts) from the same source, so
that's not quite an option...

ok, i managed to work out how to trick \layout { breakbefore } by
defining a scheme variable to either true or false in the skeleton
files and that works fine.

now i have the problem that for the a5 landscape version i'm seriously
squashing some layout with \context {\Score  \override
NonMusicalPaperColumn #'line-break-system-details} -- i don't want
this squashing in the a4 portrait mode though.

i've tried some weird and wonderful scheme hacks (creating a list
based on whether the breakafive variable is set or not and passing
that to break-system-details, but guile complains). so, basically i'm
stuck. which means i need to create different input files which differ
in 1 line for the a5 landscape format (with ~1700 lines of lily input
just for the layout, i don't want to do this, so the lines get
uncommented or commented out, depending on what i'm generating, but
this is not satisfactory... :/)

any ideas? thanks for your input,
sb
