= Ruby Packaging Standard

The aim of this document is two-fold.  First, to specify a common
structure of how a Ruby package distributed as source (that is, but
not limited to, development directories, version-controlled
repositories, .tar.gz, Gems, ...) should conform to.

Second, to document common and proven ways to structure Ruby packages,
and to point out certain anti-patterns that sneaked into common use.
It is by intent not to innovate.

/* This is when a refactoring really pays off.
 *
 * In order to make your code more modular, avoid hard-coding assumptions (or refactor them away).
 * The most fundamental, anti-modular assumption in Object-Oriented software is the concrete type of objects.
 * Any time you write "new MyClass" in your code (or in Ruby MyClass.new) you've hardcoded
 * an assumption about the concrete class of the object you're allocating. These makes it impossible, for example,
 * for someone to later add logging around method invocations of that object, or timeouts, or whatever.
 * 
 * In a very dynamic language like Ruby, open classes and method aliasing mitigate this problem, but
 * they don't solve it. If you manipulate a class to add logging, all instances of that class will have
