/***********************************************************************
ssx/main.cpp - Main driver module for ssqlsxlat, which does several
data translations related to the SSQLSv2 mechanism of MySQL++. The
primary one is SSQLSv2 language files (*.ssqls) to C++ source code,
but there are others. Run "ssqlsxlat -?" to get a complete list.
