8## Note for tuning: In theory you could strip down the resulting packages size
9## a lot, if you removed gforth and gforth-fast executables and only included
10## the (somewhat slower) gforth-itc and/or gforth-ditc interpreter binary that
11## rely on classic indirect threaded code without the (code-bloating) engine
12## optimizations.
13##
14## Also we could create multiple packages here 'gforth-minimal' and 'gforth'?
