Re: Scripting within GNUstep

Hi Yavor,

Thank you for the instructive answer.
I simply found the whole 'documentation' and the 'reference' folder in 
the source folder of 'libs-steptalk'.
Also the 'Shell' folder under 'Examples': I built and installed 
stshell I was missing.
So I have now all is needed to learn and practice about scripting 
within GNUstep.
