* Revision 1.5 2014/10/13 08:52:39 j_novak
* Lorene classes and functions now belong to the namespace Lorene.
*
* Revision 1.4 2014/10/06 15:12:57 j_novak
* Modified #include directives to use c++ syntax.
*
* Revision 1.3 2002/10/16 14:36:31 j_novak
* Reorganization of #include instructions of standard C++, in order to
* use experimental version 3 of gcc.
*
* Revision 1.2 2001/12/04 21:27:52 e_gourgoulhon
*
* All writing/reading to a binary file are now performed according to
* the big endian convention, whatever the system is big endian or
* small endian, thanks to the functions fwrite_be and fread_be
