Gennady,

The C++ class used for this is OGRSpatialReference and it is part of
my GDAL/OGR library (http://www.gdal.org).  The OGRSpatialReference
class supports translating between a variety of coordinate system
formats, including WKT (it's internal representaton), PROJ.4, GML
(weak really), and a few other esoteric options.  A reasonable primer
on the services is available at:

   http://www.gdal.org/ogr/osr_tutorial.html

Incidentally, this is the class uses to generate the PROJ.4 "epsg" init
file.

Best regards,
