# Description   : A script to build a package from a clearcase element

#                 The script will:

#                   Create a clearcase view

#                   Checkout the files

#                   Locate the build file

#                   Build the packages

#                   Install packages

#                   Remove the view

#

#               The script can do a lot of other things too.
