<prereq id="GUID-FFA3AFA4-7417-4B3E-85FC-8FB5613B764D">       <p>To migrate

to STLport v5, application developers can retain the existing sources, but

must make changes to the MMP files. More than just linking against STLport

v5, application developers can make use of latest features available from

STLport v5 onwards and also make use of tools support added in Symbian^3.</p>
