+ * Handling native paths.

+ * This module contains a number of functions destined to simplify
+ * working with native paths through a cross-platform API. Functions
+ * of this module will only work with the following assumptions:
+ *
+ * - paths are valid;
+ * - paths are defined with one of the grammars that this module can
+ * parse (see later);
+ * - all path concatenations go through function |join|.
