+  Description:
+    The spawner is a wrapper for spawn-fcgi that makes it easier to start multiple FCGI
+    processes running the Rails dispatcher. The spawn-fcgi command is included with the lighttpd 
+    web server, but can be used with both Apache and lighttpd (and any other web server supporting
+    externally managed FCGI processes).
+
+    You decide a starting port (default is 8000) and the number of FCGI process instances you'd 
+    like to run. So if you pick 9100 and 3 instances, you'll start processes on 9100, 9101, and 9102.
+
+  Examples:
+    spawner               # starts instances on 8000, 8001, and 8002
+    spawner -p 9100 -i 10 # starts 10 instances counting from 9100 to 9109
+  EOF
