# This script is a wrapper for calling the ANT with hostint tasks. 
# The ANT hostinit tasks replace some functions of the hostinit
# ccm command (ccm hostinit .....), implemented by 
# com/arsdigita/packaging/Hostinit.java class
# Specifically it copies addon packages into an existing aplaws
# installation and checks for prerequisites and consistency condition.

# Variables for directories.
# The path are relative to the bin directory of the CCM installation. This
# means that this script has to be executed from the bin directory. If you
# want to use this script from another directory, or include it into your 
# PATH, you have to adjust the paths.
