 * (i.e. sites/somesite/modules/).  The returned array will be keyed
 * using the key specified (name, basename, filename).  Using name or
 * basename will cause site-specific files to shadow files in the
 * default directories.  That is, if a file with the same name appears
 * in both location, only the site-specific version will be included.
 *
 * @param $mask
 *   The regular expression of the files to find.
 * @param $directory
 *   The subdirectory name in which the files are found.  For example,
 *   'modules' will search in both modules/ and
 *   sites/somesite/modules/.
 * @param $key
 *   The key to be passed to file_scan_directory().
675 676
 * @param $min_depth
 *   Minimum depth of directories to return files from.
