# deployConsole.py - profile creation script for deploying isclite
#------------------------------------------------------------------------------
# Required Arguments:
#    cell   - name of the cell on which to install isclite
#    node   - name of the node on which to install isclite
#    server - name of the server on which to install isclite
#
# Example:
# wsadmin.sh -f deployConsole.py -cell myNodeCell -node myNode -server server1
#
# Notes:
# This script is only inteded to be executed during profile creation
#------------------------------------------------------------------------------
# History:
# 
#    2006/01/26 - wolfpa@us.ibm.com
#    Initial version of deployConsole.py created to replace functionality
#    within deployAdminConsole.ant config action.
