+
+<vserver> is the name of a vserver.
+
+Possible commands are:
+ start [--nodeps] <start-vservers-opts>*
+ ... starts the specified vserver
+ stop [--nodeps] <start-vservers-opts>*
+ ... stops the specified vserver
+ restart ... restarts the specified vserver; this is the subsequent
+ execution of a synchronized 'stop' and a 'start'
+ condrestart ... restarts the vserver when it is running already
+ suexec <user> <shell-command> <args*>
+ ... executes a command as the specified user in the vserver
+ exec <shell-command> <args*>
+ ... executes a command as root in the vserver
+ enter ... executes the configured shell in the vserver
+ chkconfig <chkconfig-options*>
+ ... modifies the init-system; currently, only Red Hat's
+ chkconfig is supported
+ running ... succeeds iff the vserver is running
+ status ... gives out some human readable status information about
+ the vserver, and succeeds iff the vserver is running
+
+ build <buildopts>*
+ ... builds a new vserver from scratch
+
+ unify [-R]
+ ... (de)unify vserver
+
+ pkg install <pkg>
+ ... installs package(s) in the vserver
+
+ apt-get,apt-config,apt-cache <apt-opts>*
+ ... execute the apt-* command for the given vserver
+ rpm <rpm-opts>*
+ ... execute the rpm command for the given vserver
+
+ pkgmgmt externalize|internalize [-y]
+ ... externalize or internalize the package-management for the
+ given vserver. 'Externalize' means that package metadata
+ and management tools (apt-get,rpm) are living in the host,
+ while 'internalize' means that data and programs from the
+ vserver will be used.
+
+ unify <vunify-opts>*
+ ... unify the vserver with its reference vserver(s).
