#
# Description:
# The xcatsnap command gathers configuration, log and trace information
# about the xCAT components that are installed. This command only collects
# the data on the local node on which this command is run.
#
# This command is typically executed when a problem is encountered with
# any of these components in order to provide service information to the
# IBM Support Center.
#
# This command should only be executed at the instruction of the IBM
# Support Center.
# Syntax:
# perl xcatsnap [-h] [-v] [-B] [-d output_directory]
#
# Flags:
# -h displays the usage of this command to standard output.
# -v displays the version of this tool.
# -B Bypass mode.
# -d is used to specify the output directory,
# otherwise the default directory is /tmp/xcatsnap
#
# Ouput:
# tar file : xcatsnap.host_name.nnnnnnnn.tar.gz
# log file : xcatsnap.host_name.nnnnnnnn.log
# (where host_name is the base name of the host name of the
# node on which the command is running; nnnnnnnn is a timestamp).
#
# Exit Status:
# 0 - Command ran successfully
# 1 - error occured
#
# Security:
# This command can only be run by a root user.
