Chris@0: Drupal Components are independent libraries that do not depend on the rest of
Chris@0: Drupal in order to function.
Chris@0: 
Chris@0: Components MAY depend on other Drupal Components or external libraries/packages,
Chris@0: but MUST NOT depend on any other Drupal code.
Chris@0: 
Chris@0: In other words, only dependencies that can be specified in a composer.json file
Chris@0: of the Component are acceptable dependencies.  Every Drupal Component presents a
Chris@0: valid dependency, because it is assumed to contain a composer.json file (even
Chris@0: if it may not exist yet).
Chris@0: 
Chris@0: Each Component should be in its own namespace, and should be as self-contained
Chris@0: as possible.  It should be possible to split a Component off to its own
Chris@0: repository and use as a stand-alone library, independently of Drupal.
