#
# This include will remove a debug point from the current GLOBAL or SESSION
# debug variable without changing other debugging flags set.
#
# ==== Usage ====
#
# --let $debug_point= debug_point
# [--let $debug_point_silent= 1]
# [--let $debug_type= GLOBAL | SESSION]
# [--let $debug_if_exists= 1]
# --source extra/rpl_tests/remove_debug_point.inc
#
# Parameters:
# $debug_point
# The debug point to be removed.
#
# $debug_point_silent
# By default, this script prints the name of the debug point. If
# this parameter is set, it does not print anything.
#
# $debug_type
# If the debug variable to be changed is the GLOBAL or SESSION one.
# The default (if not specified one) is GLOBAL.
#
# $debug_if_exists
# By default, this script fails if the debug symbol does not exist.
# If this variable is set, the error is omitted.
