5	# Provide user, group, and mode information for devices. If a regex matches
6	# the device name provided by sysfs, use the appropriate user:group and mode
7	# instead of the default 0:0 660.

9	# Syntax:
10	# [-][ENVVAR=regex;]...devicename_regex user:group mode [=path]|[>path]|[!] [@|$|*cmd args...]
11	# [-][ENVVAR=regex;]...@maj,min[-min2] user:group mode [=path]|[>path]|[!] [@|$|*cmd args...]
12	# [-]$ENVVAR=regex user:group mode [=path]|[>path]|[!] [@|$|*cmd args...]
13	#
14	# [-]: do not stop on this match, continue reading mdev.conf
15	# =: move, >: move and create a symlink
16	# !: do not create device node
17	# @|$|*: run cmd if $ACTION=remove, @cmd if $ACTION=add, *cmd in all cases
