| * Revision 1.2 1999/12/02 19:02:57 roddey |
| * Get rid of a few statically defined XMLMutex objects, and lazy eval them |
| * using atomic compare and swap. I somehow let it get by me that we don't |
| * want any static/global objects at all. |
| * |
| * Revision 1.1.1.1 1999/11/09 01:05:39 twl |
| * Initial checkin |

| * Revision 1.3 1999/11/08 20:45:19 rahul |
| * Swat for adding in Product name and CVS comment log variable. |
