# CallWeaver.org CLI wrapper - version 1.0 (transitional)
#
#  First release January 2007.
#  This script is hereby released into the Public Domain.
#  NOTE: THIS SOFTWARE COMES WITHOUT ANY WARRANTY WHATSOEVER.
#
# Description
#  In preparation of separating daemon and CLI this script is
#  provided as a CLI wrapper to invoke CallWeaver.org's CLI mode
#  as if it was a separate CLI utility. Its purpose is to get
#  users accustomed to the idea of a standalone CLI utility.
