4ae5bbc4 | 18 | Revision 1.9 2002/10/14 14:57:00 hristov |
19 | Merging the VirtualMC branch to the main development branch (HEAD) | |
20 | ||
b9d0a01d | 21 | Revision 1.7.6.1 2002/08/28 15:06:50 alibrary |
22 | Updating to v3-09-01 | |
23 | ||
24 | Revision 1.8 2002/08/21 22:04:27 nilsen | |
25 | Added data member to SPD cluters and made related modifications to the | |
26 | SPD Cluster finders. Generaly cleanded up some of the code. | |
27 | ||
9e1e0cd7 | 28 | Revision 1.7 2001/10/19 21:32:35 nilsen |
29 | Minor changes to remove compliation warning on gcc 2.92.2 compiler, and | |
30 | cleanded up a little bit of code. | |
