 ## Notes
 
 * `dirname` is the relative path from the base directory set by `gulp.src` to the filename.
   * `gulp.src()` uses glob-stream which sets the base to the parent of the first directory glob (`*`, `**`, [], or extglob). `dirname` is the remaining directories or `./` if none. glob-stream versions >= 3.1.0 (used by gulp >= 3.2.2) accept a `base` option, which can be used to explicitly set the base.
   * `gulp.dest()` renames the directories between `process.cwd()` and `dirname` (i.e. the base relative to CWD). Use `dirname` to rename the directories matched by the glob or descendents of the base of option.
-* `basename` is the filename without the extension like path.basename(filename, path.extname(filename)).
-* `extname` is the file extension including the '.' like path.extname(filename).
-* when using a function, a second `file` argument is provided with the whole context and original file value
-* when using a function, if no `Object` is returned then the passed parameter object (along with any modifications) is re-used
