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