Hi, I'd like to deploy an client ruby application by copying the "c:\ruby" folder to the target computers. It works fine, except that c:\ruby is 177 MB big, and full of things that are not necessary at all on client computers. I have tried keeping the following folders: - "c:\ruby\." - "c:\ruby\bin" - "c:\ruby\lib" It works, but I'd like to know if anyone has a more "scientific" approach to that problem. What folders are absolutely needed? Note that I know about rubyscript2exe.rb; it works just fine for small applications, but it's not an option in this case. Thanks! Philippe
