// Description this class emulates the Smarty API to attempt to enable
// upgrading to flexy. (eg. for use with flexy templates (that have been
// converted using the SmartyConverter Compiler.
//
// I've no idea how complete this will end up being..
//
// Technically Smarty is LGPL - so theortically no code in here should
// use the copy & paste the original smarty code....
//
// to use as a full emulator :
// try
// class Smarty extends HTML_Template_Flexy_SmartyAPI {
// function Smarty() { parent::construct(); }
// }
// not implemented:
