+usage: atomix-gen-config [-h] [-s PARTITION_SIZE] [-n NUM_PARTITIONS]
+                         [node_ip] [filename] [node_ip [node_ip ...]]
+
+Generate the partitions json file given a list of IPs or from the $OCC*
+environment variables.
+
+positional arguments:
+  filename              File to write output to. If none is provided, output
+                        is written to stdout.
+  node_ip               IP Address(es) of the node(s) in the cluster. If no
+                        IPs are given, will use the $OCC* environment
+                        variables. NOTE: these arguemnts are only processed
+                        after the filename argument.
+
+optional arguments:
+  -h, --help            show this help message and exit
+  -s PARTITION_SIZE, --partition-size PARTITION_SIZE
+                        Number of nodes per partition. Note that partition
+                        sizes smaller than 3 are not fault tolerant. Defaults
+                        to 3.
+  -n NUM_PARTITIONS, --num-partitions NUM_PARTITIONS
+                        Number of partitions. Defaults to the number of nodes
+                        in the cluster.
