+/**
+* This is the dynamic loader for the library. It checks whether you have
+* the mbstring extension available and includes relevant files
+* on that basis, falling back to the native (as in written in PHP) version
+* if mbstring is unavailabe.
+*
+* It's probably easiest to use this, if you don't want to understand
+* the dependencies involved, in conjunction with PHP versions etc. At
+* the same time, you might get better performance by managing loading
+* yourself. The smartest way to do this, bearing in mind performance,
+* is probably to "load on demand" - i.e. just before you use these
+* functions in your code, load the version you need.
+*
+* It makes sure the the following functions are available;
+* utf8_strlen, utf8_strpos, utf8_strrpos, utf8_substr,
+* utf8_strtolower, utf8_strtoupper
+* Other functions in the ./native directory depend on these
+* six functions being available
+* @package utf8
