Script for generating stub dynamic libraries for cross compilation
#!/usr/bin/env ruby
# This script can create stub C libraries that are useful in cross-compilation
# tasks.

# This will generate a stub file, a compiled shared object for the local system,

# doesn't have the library of matter, and executed, resulting in a shared object
# that represents a stub of the original library. A stub library has all the
