# Infrastructure support for the rc.d script system (pkgtools/rc.subr).
#
# Package-settable variables:
#
# RCD_SCRIPTS
#	List of the basenames of the rc.d scripts.  The example rc.d
#	script must be found in ${PREFIX}/share/examples/rc.d, and
#	the script will be copied into ${RCD_SCRIPTS_DIR} with
#	${RCD_SCRIPTS_MODE} permissions.
#
# RCD_SCRIPTS_DIR
#	The location of the copied rc.d scripts.
#
#	Possible: any path
#	Default: /etc/rc.d
#
# RCD_SCRIPTS_EXAMPLEDIR
#	The location of the example rc.d scripts.  This location must
#	be a relative path to ${PREFIX}.
#
#	Possible: any path
#	Default: share/examples/rc.d
#
# RCD_SCRIPTS_MODE
#	The file mode of the copied rc.d scripts.
#
#	Possible: any file mode
#	Default: 0755
#
# RCD_SCRIPTS_SHELL
#	The shell used to run the rc.d scripts.
#
#	Possible: any shell path
#	Default: ${SH}
#
# RCD_SCRIPT_SRC.<script>
#	The source file for the rc.d script with basename <script>
#	before installation; the source file is put through variable
#	substitution to generate the target rc.d script.  If the
#	source file is not present, then no rc.d script is generated.
#
#	Possible: any path
#	Default: ${FILESDIR}/<script>.sh
