Revision 1.18 2004/02/22 09:54:21 tournois Change years on the copyright. Revision 1.17 2004/01/29 20:52:35 tournois doc and tutorial. Revision 1.16 2004/01/18 11:40:58 tournois Add the pattern facet. Revision 1.15 2003/12/10 20:32:18 tournois Fix somes bugs about attributes and now tests are all check. Revision 1.14 2003/12/09 19:57:28 tournois Fix some bugs about attributes classes. Revision 1.13 2003/12/05 13:04:41 hfp adapt supplied functions Revision 1.12 2003/12/05 10:42:53 hfp completed Revision 1.11 2003/12/04 14:44:10 hfp shortcut/uri-mapping includes default namespace ns_map swaps key with value -> faster find for main use-case throwing error in some cases interface is based on map (insert, fiind) mis-use of special values on return removed (find etc.) size() returns an size_t (unsigned) Revision 1.10 2003/12/03 12:28:46 hfp swap, copy construction and assignment Revision 1.9 2003/11/19 20:52:54 tournois Add new manipulator for stag and etag. Correct bugs and add tests.
