+# Description
+#     Scheduler for network distributed compilations using wmake.
+#     - WM_HOSTS contains a list of hosts and number of concurrent processes
+#     eg,
+#        export WM_HOSTS="hostA:1 hostB:2 hostC:1"
+#     - WM_COLOURS contains a list of colours to cycle through
+#        export WM_COLOURS="black blue green cyan red magenta yellow"
+#
+#     Sources the relevant cshrc/bashrc if not set.
+#
+#     WM_PROJECT_DIR, WM_PROJECT and WM_PROJECT_VERSION will have been set
+#     before calling this routine
+#
+# Usage
+#     wmakeScheduler COMMAND
+#         run 'COMMAND' on one of the slots listed in WM_HOSTS
+#
+#     wmakeScheduler -count
+#         count the total number of slots available in WM_HOSTS
+#         eg,  WM_NCOMPPROCS=$(wmakeScheduler -count)
