Dear Giovanni,
 is quite dangereous (as you observe in the readme) to allow arbitrary 
scritps to execute. One should make available to the executing script only 
the commands needed to create a picture (and maybe mathematical/string pure 
functions). This is possible since load take (if I remember correctly) as 
argument an 'environment' or 'module' with the available bindings. This would 
make execution safe. 

That is a nice exercise in scheme/guile for you. :)
