I have a ruby script with 5 gem dependencies that I require to be transformed (or compiled) into an executable that can run on Windows or Mac. I would assume that rubyscript2exe or crate would be used for this task, however the contractor it is at the contractor's discretion what tool is used.
The script must be able to run on either platform without any additional files being installed (it will be distributed via the internet). It won't need a gui as it will be run from the command line.
This job is not to write the script. Merely to take the written script and transform it to an executable.
UPDATE: This task is no longer to produce a Mac executable. Just a windows standalone executable.
