 * $Log: des_prof_cmp.C,v $
 * Revision 1.6  2008/08/19 06:42:00  j_novak
 * Minor modifications to avoid warnings with gcc 4.3. Most of them concern
 * cast-type operations, and constant strings that must be defined as const char*
 *
 * Revision 1.5  2004/03/25 10:29:25  j_novak
 * All LORENE's units are now defined in the namespace Unites (in file unites.h).
 *
 * Revision 1.4  2004/02/12 16:20:36  e_gourgoulhon
 * Functions des_profile for Scalar's are now in the new file
 *  des_prof_scalar.C
 *
 * Revision 1.3  2004/02/04 14:28:14  p_grandclement
 * Ajout de la version Scalar de des_profile
 *
 * Revision 1.2  2003/06/03 09:59:35  e_gourgoulhon
 * Added a new des_profile with scale and nomx in arguments
