*
* 17-Jun-2004 Ziad Al Bawab (ziada@cs.cmu.edu) at Carnegie Mellon University
* Created
* $Log$
* Revision 1.1 2006/04/05 20:27:30 dhdfu
* A Great Reorganzation of header files and executables
*
* Revision 1.10 2006/03/03 20:02:38 arthchan2003
* Removed C++ styles comment. This will make options -ansi and -std=c89 happy
*
* Revision 1.9 2006/02/23 04:05:21 arthchan2003
* Merged from branch SPHINX3_5_2_RCI_IRII_BRANCH: fixed dox-doc.
*
*
* Revision 1.6.4.1 2005/07/05 06:46:23 arthchan2003
* 1, Merged from HEAD. 2, fixed dox-doc.
*
* Revision 1.8 2005/07/04 20:57:53 dhdfu
* Finally remove the "temporary hack" for the endpointer, and do
* everything in logs3 domain. Should make it faster and less likely to
* crash on Alphas.
*
* Actually it kind of duplicates the existing GMM computation functions,
* but it is slightly different (see the comment in classify.c). I don't
* know the rationale for this.
*
* Revision 1.7 2005/07/02 04:24:45 egouvea
* Changed some hardwired constants to user defined parameters in the end pointer. Tested with make test-ep.
*
* Revision 1.6 2005/06/21 21:06:47 arthchan2003
* 1, Fixed doxygen documentation, 2, Added keyword. 3, Change for mdef_init to use logging.
*
* Revision 1.3 2005/06/15 06:48:54 archan
* Sphinx3 to s3.generic: 1, updated the endptr and classify 's code, 2, also added
*
