Defines a Drupal stream wrapper extension.
Provides a Drupal interface and classes to implement PHP stream wrappers for public, private, and temporary files. Extends the StreamWrapperInterface with methods expected by Drupal stream wrapper classes.
A stream wrapper is an abstraction of a file system that allows Drupal to use the same set of methods to access both local files and remote resources.
Note that PHP 5.2 fopen() only supports URIs of the form "scheme://target" despite the fact that according to RFC 3986 a URI's scheme component delimiter is in general just ":", not "://". Because of this PHP limitation and for consistency Drupal will only accept URIs of form "scheme://target".
