=head1 DESCRIPTION |
| 12 |
|
|
|
| 13 |
|
|
This module provides an assortment of network-global functions: group name |
| 14 |
|
|
registration and non-local locks. |
| 15 |
|
|
|
| 16 |
|
|
It will also try to build and maintain a full mesh of all network nodes. |

While it isn't mandatory to run the global services, running it on one |
| 19 |
|
|
node will automatically run it on all nodes. |
