-/** This is an alternative implementation of QCString. It provides basically
- *  the same functions but uses less memory for administration. This class
- *  is just a wrapper around a plain C string requiring only 4 bytes "overhead".
- *  QCString features sharing of data and stores the string length, but 
- *  requires 4 + 12 bytes for this (even for the empty string). As doxygen 
- *  uses a LOT of string during a run it saves a lot of memory to use a 
- *  more memory efficient implementation at the cost of relatively low
- *  runtime overhead.
