+/**
+ * This is the Drush "finder" script, which is one part of the
+ * Drush dispatching chain.  This is the script that
+ * should appear in your global $PATH, or, if using Composer
+ * (as usually the case), will be found in your vendor/bin directory.
+ *
+ *
+ * - Never copy this script to your site root. Copy examples/drush instead.
+ *
+ * - Never copy this script to a directory other than its install directory.
+ * Symlink to it instead.
+ *
+ *
+ * OVERVIEW OF DRUSH FINDER / WRAPPER / LAUNCHER SCRIPTS
+ *
+ * When the user types "drush", up to three scripts might be
+ * involved in the initial launch:
+ *
+ *   "drush finder" -> "drush wrapper" -> "drush launcher".
+ *
+ * Brief description of each:
+ *
+ *  - Drush finder:   Finds the right Drush script and calls it.
+ *  - Drush wrapper:  Contains user customizations to options.
+ *  - Drush launcher: Excutes drush.php.
+ *
+ * A full explanation of each script follows.
+ *
+ *
+ * DRUSH FINDER
+ *
+ * - The "drush" script on the user's global $PATH
+ * - It's goal is to find the correct site-local Drush to run.
+ *
+ * The Drush finder will locate the correct site-local Drush to use
+ * by examining:
+ *
+ *   a) The --root option
+ *   b) The site set via `drush site set` in the current terminal
+ *   c) The cwd
+ *
+ * If no site-local Drush is found, then the global Drush will be
+ * used.  The Drush finder assumes that the global Drush is the
+ * "Drush launcher" found in the same directory as the Drush finder itself.
+ *
+ * If a site-local Drush is found, then the Drush finder will call
+ * either the "Drush wrapper", if it exists, or the "Drush launcher" if
+ * there is no wrapper script.
+ *
+ *
+ * DRUSH WRAPPER
+ *
+ * - The drush.wrapper script that the user optionally copies and edits.
+ * - Its goal is to allow the user to add options when --local is in use
+ *
+ * The Drush "wrapper" is found at examples/drush.wrapper, and may optionally
+ * be copied to __ROOT__ by the user.  It may be named either
+ * "drush" or "drush.wrapper".  It will call the "Drush launcher"
+ * for the same site that it is located in.  It adds the --local flag; the
+ * user is encouraged to add other options to the "Drush wrapper", e.g. to set
+ * the location where aliases and global commandfiles can be found.
+ * The Drush "finder" script always calls the "Drush wrapper" if it exists;
+ * however, if the user does not want to customize the early options of
+ * the site-local Drush (site-alias locations, etc.), then the wrapper does not
+ * need to be used.
+ *
+ *
+ * DRUSH LAUNCHER
+ *
+ * - The "drush.launcher" script in vendor/bin
+ * - The bash script formerly called "drush"
+ *
+ * The "Drush launcher" is the traditional script that identifies PHP and
+ * sets up to call drush.php.  It is called by the "Drush wrapper", or
+ * directly by the "Drush launcher" if there is no "Drush wrapper" in use.
+ *
+ *
+ * LOCATIONS FOR THESE SCRIPTS
+ *
+ *   "Drush finder"   :  __ROOT__/vendor/bin/drush           (composer install)
+ *                       __DRUSH__/drush                     (source)
+ *
+ *   "Drush wrapper"  :  __ROOT__/drush                      (copied by user)
+ *                       __DRUSH__/examples/drush.wrapper    (source)
+ *
+ *   "Drush launcher" :  __ROOT__/vendor/bin/drush.launcher  (composer install)
+ *                       __DRUSH__/drush.launcher            (source)
+ *
+ *
+ * BACKEND CALL DISPATCHING
+ *
+ * Backend calls are typically set up to call the "drush" script in the $PATH,
+ * or perhaps some might call __ROOT__/vendor/bin/drush directly, by way
+ * of the "drush-script" element in a site alias.  In either event, this is
+ * the "drush finder" script.
+ *
+ * The backend call will always set --root.  The "Drush finder" script
+ * always favors the site-local Drush stored with the site indicated by the
+ * --root option, if it exists.  If there is no site-local Drush, then the
+ * "Drush finder" will behave as usual (i.e., it will end up calling the
+ * "Drush launcher" located next to it).
+ *
+ * This should always get you the correct "Drush" for local and remote calls.
+ * Note that it is also okay for aliases to specify a path directly to
+ * drush.launcher, in instances where it is known that a recent version of
+ * Drush is installed on the remote end.
