In the past I've used a very simple construct:

notes = { ... }

music = {
    \tag Bassoon \notes
    \tag BCl \transpose bes, c' { \notes }
}

instrument = Bassoon					% could be Bassoon or BCl (bassclarinet) in  
my case

\score
        \keepWithTag \instrument \music
        \layout {}
}

It is sort of hard-coded, BUT I could vary the instrument by creating  
a small file in which I stated this instrument and just included that  
file again in the Lilypond framework-file. With an external Makefile I  
steered what should be done by generating (or copying) this include- 
file and then running the lilypond command on the framework.
