Ruby tries to load the library named string, returning true if successful. If the filename does not resolve to an absolute path, it will be searched for in the directories listed in $:. If the file has the extension “.rb”, it is loaded as a source file; if the extension is “.so”, “.o”, or “.dll”, or whatever the default shared library extension is on the current platform, Ruby loads the shared library as a Ruby extension. Otherwise, Ruby tries adding “.rb”, “.so”, and so on to the name. The name of the loaded feature is added to the array in $“. A feature will not be loaded if its name already appears in $”. The file name is converted to an absolute path, so “require ‘a’; require ‘./a”’ will not load a.rb twice.
