Ruby Facets

Ruby Facets is a library for Ruby that adds to the API language standard a number of features that are handy to have on hand from time to time.

The library is divided into two large parts:

• CORE takes advantage of the fact that Ruby is a dynamic language (mistranslation of the English term reflective) to expand existing classes of the standard library;
• MORE provides additional modules and classes, among them Units, a large set of methods for converting quantities between units of measurement of the international system. Units also provides currency exchange updated in real time via web service.
