34  * Revision 1.8 2014/10/13 08:53:22 j_novak
35  * Lorene classes and functions now belong to the namespace Lorene.
36  *
37  * Revision 1.7 2014/10/06 15:16:05 j_novak
38  * Modified #include directives to use c++ syntax.
39  *
40  * Revision 1.6 2008/08/19 06:42:00 j_novak
41  * Minor modifications to avoid warnings with gcc 4.3. Most of them concern
42  * cast-type operations, and constant strings that must be defined as const char*
43  *
44  * Revision 1.5 2004/03/25 10:29:25 j_novak
45  * All LORENE's units are now defined in the namespace Unites (in file unites.h).
46  *
47  * Revision 1.4 2004/02/12 16:20:36 e_gourgoulhon
48  * Functions des_profile for Scalar's are now in the new file
49  * des_prof_scalar.C
50  *
51  * Revision 1.3 2004/02/04 14:28:14 p_grandclement
52  * Ajout de la version Scalar de des_profile
53  *
54  * Revision 1.2 2003/06/03 09:59:35 e_gourgoulhon
55  * Added a new des_profile with scale and nomx in arguments
