+ This String class provide base functionality for C++ like 8-Bit
+ character array handling. The advantage of this class is, that it
+ handle all the memory management for you - and it do it
+ more efficient. If you assign a string to another string, the
+ data of both strings are shared (without any copy operation or
+ memory allocation) as long as you do not change the string. This class
+ stores also the length of the string, so that many operations are
+ faster as the C-str-functions.
+
+ This class provides only readonly string handling. So you could create
+ a string and you could only query the content from this string.
+ It provides also functionality to change the string, but this results
+ in every case in a new string instance (in the most cases with an
+ memory allocation). You don't have functionality to change the
+ content of the string. If you want to change the string content, then
+ you should use the OStringBuffer class, which provides these
+ functionalities and avoid too much memory allocation.
+
+ The design of this class is similar to the string classes in Java
+ and so more people should have fewer understanding problems when they
+ use this class.
