tools/tungsten-installer does not issue warnings when the master-host is incorrect

What steps will reproduce the problem?
1. Typo in the master-host to a server during the tools/tungsten-installer
Servers intended: myhost1(master), myhost2(slave). 
 --master-host=r1 rather than myhost1 and --cluster-hosts=myhost1,myhost2
r1 is a valid server. In my test I used myhost3 as r1 was not available. 
myhost3 was not running tungsten replicator.

2. Typo mis-match where --master-host=s1 (non-existent host) and  
--cluster-hosts=myhost1,myhost2

What is the expected output?
a clear warning/error message with reason why.

What do you see instead?
NAME              VALUE
----              -----

Finished services command...

As a new user I wasn't sure why it was OFFLINE nor where to find the error.

For type 1 (server exists) trepsvc.log had this:
INFO   | jvm 1    | 2011/06/23 21:34:37 | 2011-06-23 21:34:36,963 INFO

for type 2 (non-existent server master-host=s1 which is unknown to myhost1 
where installer is run)

current state: state=OFFLINE:ERROR event=OfflineNotification

What is the possible cause?
user error

What is the proposed solution?
installer parses the arguments and makes sure that the first server in 
cluster-hosts = master-host
