The different "batch" systems available are described in the $KVROOT/KVFiles/.kvrootrc or the user's $HOME/.kvrootrc, as in the following examples:

# Batch systems
BatchSystem:     Xterm
Xterm.BatchSystem.Title:    Execute task in an X-terminal window
+BatchSystem:     Linux
Linux.BatchSystem.Title:    Execute task in background with output stored in log file
#+BatchSystem:     BQS
#BQS.BatchSystem.Title:   Use CCIN2P3 BQS batch system
#BQS.BatchSystem.DefaultJobTime:   4000
#BQS.BatchSystem.DefaultJobMemory:   256MB
#BQS.BatchSystem.DefaultJobDisk:   100MB

For each named batch system, there must be a corresponding plugin which defines the actual class to use:

#Plugins for batch systems
Plugin.KVBatchSystem:    Xterm    KVRootBatch     KVMultiDet    "KVRootBatch()"
+Plugin.KVBatchSystem:    Linux    KVLinuxBatch     KVMultiDet    "KVLinuxBatch()"
+Plugin.KVBatchSystem:    BQS    KV_CCIN2P3_BQS     KVMultiDet    "KV_CCIN2P3_BQS()"

The "default" batch system is defined as follows:

#Default batch system
Default.BatchSystem:   Xterm

It can be accessed via the global pointer to the batch system manager:

KVBatchSystem* default = gBatchSystemManager->GetDefaultBatchSystem();
