+# VARIABLES
+#
+
+
+# global environment variables used by apache2-maintscript-helper:
+# * APACHE2_MAINTSCRIPT_DEBUG:
+#				set this to any non-zero value to get debug output
+# * APACHE2_MAINTSCRIPT_HELPER_QUIET:
+#				set this to any non-zero value to omit any output
+# * EXPORT_APACHE2_MAINTSCRIPT_HELPER:
+#				will be defined by apache2-maintscript-helper
+#				to avoid inclusion loops. Do not set this
+#				variable manually
+# * APACHE2_NEED_ACTION:
+#				will be defined if a function call wants to
+#				override the behavior of apache2_needs_action.
+#				Do not rely on this variable. It is considered
+#				an implementation detail.
+# * APACHE2_MAINTSCRIPT_NAME
+# * APACHE2_MAINTSCRIPT_PACKAGE
+# * APACHE2_MAINTSCRIPT_METHOD
+# * APACHE2_MAINTSCRIPT_ARGUMENT
+#				these variables contain information about the
+#				maintainer script which is calling the
+#				maintscript-helper. It contains arguments which
+#				dpkg supplies to maintainer scripts and similar
+#				information. These variables are an
+#				implementation detail and not to be changed.
+#
+#				You might want to set them manually only if you
+#				are calling apache2-maintscript-helper from
+#				some place which does not preserve the original
+#				script arguments for example when calling from
+#				a subfunction instead of the main function in
+#				your maintainer script

+#	the web server in maintainer scripts.
+# Parameters:
+#	priority
+#		The message priority. Recognized values are the same as defined
+#		by syslog(3), thus: one among debug, info, notice, warning,
+#		err, crit, alert, emerg.
+#		If no known priority is recognized, the priority is set to
+#		"warning".
+#	message
+#		The message as a string. It is printed out verbatim.
+# Behavior:
+#	No message is displayed if APACHE2_MAINTSCRIPT_HELPER_QUIET is defined
+# Returns:
+#	this function always returns 0
+# Since: 2.4.1-3
