#Each line describes a rule for a user in the forms:
#
#<user> <controllers> <destination>
#<user>:<process name> <controllers> <destination>
#
#Where:
# <user> can be:
# - an user name
# - a group name, with @group syntax
# - the wildcard *, for any user or group.
# - The %, which is equivalent to "ditto". This is useful for
# multiline rules where different cgroups need to be specified
# for various hierarchies for a single user.
#
# <process name> is optional and it can be:
# - a process name
# - a full command path of a process
#
# <controller> can be:
# - comma separated controller names (no spaces)
# - * (for all mounted controllers)
#
# <destination> can be:
# - path with-in the controller hierarchy (ex. pgrp1/gid1/uid1)
#
# Note:
# - It currently has rules based on uids, gids and process name.
#
# - Don't put overlapping rules. First rule which matches the criteria
# will be executed.
#
# - Multiline rules can be specified for specifying different cgroups
# for multiple hierarchies. In the example below, user "peter" has
# specified 2 line rule. First line says put peter's task in test1/
# dir for "cpu" controller and second line says put peter's tasks in
# test2/ dir for memory controller. Make a note of "%" sign in second line.
# This is an indication that it is continuation of previous rule.
#
#
#<user> <controllers> <destination>
#
#john cpu usergroup/faculty/john/
#john:cp cpu usergroup/faculty/john/cp
#@student cpu,memory usergroup/student/
#peter cpu test1/
#% memory test2/
#@root * admingroup/
