Description&Usage.txt

Description:
  According to my research, this is the absolute minimum for a working,
  autoloader, that skips several steps that slow down the loading process.

  For example, usualy people like to use inlude_once() or require_once(),
  instead of just include or require. But this step is not neccessary,
  since spl is aware what is loaded and what not, so why waste time?

  The rest is "as usual", but boiled down to the absolute minimum. If the
  loader failed, you failed to use a propper filestructure. It's that simple!

Usage:
  As you can see, the loader will always start from the cwd(), i.e.
  "\App\Model\Class" will be translated to cwd()."App/Model/Class.php".

  Even though the cwd() function is not being used by the loader, it will
  allways use the cwd since there is a "." (dot) prepended to the path.
  (See INLCUDE_PATH in the PHP-Manual)

History:
  v7.0.1 - Minor update for 7.x Type Hinting
