# uninstall_4.0_scripts
#
# Version 1.0 (08 March 2007)
#
# Usage:
# unix% cd $ASCDS_INSTALL/contrib
# unix% ./uninstall_CIAO4_scripts
#
# Description:
#
# This script removes any files installed in $ASCDS_INSTALL/contrib
# via a CIAO Scripts tarfile released for CIAO 4.0 or later. It is 
# designed for users who wish to remove old files and directories 
# before unpacking a new CIAO Scripts tarfile.
#
# The uninstall script contains a list of the specific script files 
# to remove, along with the parameter files and documentation.  No
# other files in your CIAO distribution can be deleted by this script. 
#
# DO NOT run the script if:
#
#   - You have made custom modifications to any of the scripts and have 
#     installed these (under their original names) in $ASCDS_INSTALL/contrib.
#
#   - You wish to continue using older versions of the CIAO scripts
#
# For more information on available CIAO scripts or to download
# the latest versions, see
# http://cxc.harvard.edu/ciao/download/scripts/
