# CA License install script for Linux - wrapper around ca-lic rpm.
#
# Usage: 
# install [installpath]
#
# Where: 
# [installpath] is optional, and will be ignored if CASHCOMP is already defined.
#
# Functionality:
# The ca-lic package is relocatable based on the value of CASHCOMP.
# The value of CASHCOMP is reliably obtained via the liccaprofile common script.
# If CASHCOMP is defined the package must continue to be installed to that path.
# If CASHCOMP is not defined, the user may choose the path to install to or use the default.
# 
# It is required that certain arguments be passed to rpm when installing this package.
# It is required that this package never be uninstalled.
#
