// This example compiles using the new STL<ToolKit> from ObjectSpace, Inc.
// STL<ToolKit> is the EASIEST to use STL that works on most platform/compiler 
// combinations, including cfront, Borland, Visual C++, C Set++, ObjectCenter, 
// and the latest Sun & HP compilers. Read the README.STL file in this 
// directory for more information, or send email to [e-mail].
