design rationaleBloatfree: Gosu aims to contain everything that is necessary to write a game in clean C++ or Ruby code, yet not much more.
Reality-driven: Everything in Gosu exists for the same single reason: It was necessary for an existing project. Nothing was, and will ever be, added out of boredom.

packages ruby, the script and alldependencies together into an executable file.
works on windows, linux, OSx
rubyscript2exeFirst Step: it runs the application, checking for all the required gems and scripts, creating a list of dependencies to include in the executable
