+This is an extension that aims to implement some efficient data access
 interfaces and classes. You'll find the classes documented using php
 code in the file spl.php or in the corresponding .inc file in the examples
-subdirectory. Based on the internal implementations or the files in the 
+subdirectory. Based on the internal implementations or the files in the
 examples subdirectory there are also some .php files to experiment with.
