+SYNOPSIS
+    launch_ami.py -a ami_id [-b script_bucket] [-s script_name]
+                  [-m module] [-c class_name] [-r] 
+                  [-g group] [-k key_name] [-n num_instances]
+                  [-w] [extra_data]
+    Where:
+        ami_id - the id of the AMI you wish to launch
+        module - The name of the Python module containing the class you
+                 want to run when the instance is started.  If you use this
+                 option the Python module must already be stored on the
+                 instance in a location that is on the Python path.
+        script_file - The name of a local Python module that you would like
+                      to have copied to S3 and then run on the instance
+                      when it is started.  The specified module must be
+                      import'able (i.e. in your local Python path).  It
+                      will then be copied to the specified bucket in S3
+                      (see the -b option).  Once the new instance(s)
+                      start up the script will be copied from S3 and then
+                      run locally on the instance.
+        class_name - The name of the class to be instantiated within the
+                     module or script file specified.
+        script_bucket - the name of the bucket in which the script will be
+                        stored
+        group - the name of the security group the instance will run in
+        key_name - the name of the keypair to use when launching the AMI
+        num_instances - how many instances of the AMI to launch (default 1)
+        input_queue_name - Name of SQS to read input messages from
+        output_queue_name - Name of SQS to write output messages to
+        extra_data - additional name-value pairs that will be passed as
+                     userdata to the newly launched instance.  These should
+                     be of the form "name=value"
+        The -r option reloads the Python module to S3 without launching
+        another instance.  This can be useful during debugging to allow
+        you to test a new version of your script without shutting down
+        your instance and starting up another one.
+        The -w option tells the script to run synchronously, meaning to
+        wait until the instance is actually up and running.  It then prints
+        the IP address and internal and external DNS names before exiting.
