+=head1 NAME
+
+lxc-multigraph - Plugin to monitor LXC containers (v2.0)
+
+=head1 CONFIGURATION
+
+  [lxc-multigraph]
+    user root
+
+    # memory usage of containers drawn as
+    # stacked area charts (changes graph
+    # order) -- defaults to false
+    # env.ram_areastack true
+
+    # lxc container path, default below
+    #env.lxcpath /var/lib/lxc
+
+    # exclude the following containers
+    # (default none excluded)
+    #env.exclude container1 container2
+
+    # path where tasks sysfs files are stored,
+    # set this if the various attempts in the
+    # code don't work
+    # (default none)
+    #env.cgrouppath /sys/fs/cgroup/cpuacct/lxc/
+
+=head1 INTERPRETATION
+
+This plugin needs root privilege.
+
+This plugin has been tested with lxc 3 and
+lx2 (on Debian buster and Debian jessie,
+respectively).
+
+For the network graphs to work, you need
+to have in every container's config file
+a line defining the virtual network interface
+path (else lxc will use a random name at
+each container's start); see the lxc_netdev()
+function below.
+
+If using lxc 2, make sure you do not have cruft
+in your container config files, you can test
+it with:
+   lxc-cgroup -o /dev/stdout -l INFO -n 104 cpuacct.usage
+-- with 104 a valid lxc instance), if you
+get a warning, fix the config file.
+
+For the logins graph, you need the bc command, and,
+in each container, the users command.
+
+Tested on Debian buster and Debian jessie.
