- *
- * Revision 1.7 2000/02/24 20:00:22 abagchi
- * Swat for removing Log from API docs
- *
- * Revision 1.6 2000/02/15 23:59:07 roddey
- * More updated documentation of Framework classes.
- *
- * Revision 1.5 2000/02/15 01:21:30 roddey
- * Some initial documentation improvements. More to come...
- *
- * Revision 1.4 2000/02/06 07:47:46 rahulj
- * Year 2K copyright swat.
- *
- * Revision 1.3 2000/01/26 18:56:02 roddey
- * Needed to include XMLURL.hpp so that it compiles standalone.
- *
- * Revision 1.2 2000/01/15 01:26:16 rahulj
- * Added support for HTTP to the parser using libWWW 5.2.8.
- * Renamed URL.[ch]pp to XMLURL.[ch]pp and like wise for the class name.

- * entities out of the box. Support for socket based access is optional and
