# This command can be used to
# 1. Enable/Disbale the subroutine calling trace.
# 2. Enable the commented trace log inside a subroutine.
# The example of -c
# (daemonize,do_installm_service,do_udp_service)|xCAT::Utils(isMN,Version)|xCAT_plugin::DBobjectdefs(defls,process_request)
# If specifying a file
# (daemonize,do_installm_service,do_udp_service)
# xCAT::Utils(isMN,Version)
# xCAT_plugin::DBobjectdefs(defls,process_request)
#
# Following three lines need to be added to enable the capability of commented trace
#if (defined $ENV{ENABLE_TRACE_CODE}) {
# use xCAT::Enabletrace qw(loadtrace filter);
# loadtrace();
#}
#The commented trace can be two formats:
#1. trace section
# ## TRACE_BEGIN
# # print "In the debug\n";
# ## TRACE_END
#2. trace in single line
# ## TRACE_LINE print "In the trace line\n";
