TODO:
- * test on weird and unquantised midi input (lily-devel)
- * update doc and manpage
-
- * simply insert clef changes whenever too many ledger lines
- [to avoid tex capacity exceeded]
- * do not ever quant skips
- * better lyrics handling
- * [see if it is feasible to] move ly-classes to library for use in
- other converters, while leaving midi specific stuff here
