RubyScript2Exe creates independent executables for your Ruby scripts that can work on Windows, Linux, or Mac OS X (Darwin) systems. It compresses the executable and maintains its standalone functionality.
Also, the executable file produced by RubyScript2Exe is platform-specific. Consequently, one can stop worrying about cross-compiling. It works on Windows (RubyInstaller, MinGW, and MSWin32) and Cygwin, although the executable file in Cygwin is more significant because of static and extremely large exe's. This script includes cygwin1.dll, allowing it to run on machines without Cygwin.
RubyScript2Exe has another benefit, which is that it can save time since there are likely to be inconsistencies between different Ruby versions. Testing your script with each version is necessary unless you distribute your version of Ruby with your script. You might want to read "Distributing Ruby Applications" if you appreciate RubyScript2Exe's capabilities. It discusses how to create, pack, and distribute Ruby applications, including theory and practice.
