# install - installer for the DTraceToolkit
#
# This is a fairly simple script, most of it is error checking.
# All the script does is copy the DTraceToolkit files to another directory,
# with various checks. The user could have copied the files themselves, this
# script doesn't do anything special to them. It's really here in case
# people extrace the toolkit and go looking for an installer.
#
# 15-May-2005 Brendan Gregg Created this.
DEBUG=0 # print debug data
TEETH=1 # does this script have teeth
SLEEP=1 # pause on messages
