Almost all the code in Octave is already inside a library.  The only
code that is not is the file octave.cc.  So, if you want to create a
special purpose version of octave.cc, I suppose you can.  Just
remember that all the code distributed with Octave is GPL'd.  Will
your application be freely redistributable under terms that are
compabitible with the GPL?
