+.Dt RUNSCRIPT 8 SMM
+.Os OpenRC
+.Sh NAME
+.Nm runscript 
+.Nd a means of hooking shell commands into a service
+.Sh SYNOPSIS
+.Nm
+.Op Fl D , -nodeps
+.Op Fl d , -debug
+.Op Fl s , -ifstarted
+.Op Ar command ...
+.Sh DESCRIPTION
+.Nm
+is basically an interpreter for shell scripts which provide an easy interface
+to the often complex system commands and daemons.
+When a service runs a command it first loads it's mulitplexed configuration
+file, then it's master configuration file, then
+.Pa /etc/rc.conf
+and finally the script itself. At this point
+.Nm
+then runs the command given.
+.Pp
+Commands are defined as shell functions within the script. Here is a list of
+some functions that all runscripts have by default:
+.Bl -tag -width "RC_DEFAULTLEVEL"
+.It Ar describe
+Describes what the service does and each command the service defines.
+.It Ar start
+First we ensure that any services we depend on are started. If any needed
+services fail to start then we exit with a suitable error, otherwise call the
+supplied start function if it exists.
+.It Ar stop
+First we ensure that any services that depend on us are stopped. If any
+services that need us fail to stop then we exit with a suitable error,
+otherwise call the supplied stop function if it exists.
+.It Ar restart
+Stop and start the service, including dependencies.
+.It Ar status
+Show the status of the service. The return code matches the status, with the
+exception of "started" returning 0 to match standard command behaviour.
+.It Ar zap
+Resets the service state to stopped and removes all saved data about the
+service.
+.El
+.Pp
+The following options affect how the service is run:
+.Bl -tag -width "RC_DEFAULTLEVEL"
+.It Fl d , -debug
+Set xtrace on in the shell to assist in debugging.
+.It Fl D , -nodeps
+Ignore all dependency information the service supplies.
+.It Fl s , -ifstarted
+Only run the command if the service has been started.
+.It Fl q , -quiet
+Turns off all informational output the service generates.
+Output from any non OpenRC comands is not affected.
+.It Fl v , -verbose
+Turns on any extra informational output the service generates.
+.El
+.Pp
+The following variables affect the service script:
+.Bl -tag -width "RC_DEFAULTLEVEL"
+.It Ar extra_commands
+Space seperated list of extra commands the service defines.
+.It Ar extra_started_commands
+Space seperated list of extra commands the service defines. These only work if
+the service has already been started.
+.It Ar description
+String describing the service.
+.It Ar description_$command
+String describing the extra command the.
+.It Ar command
+Daemon to start or stop via
+.Nm start-stop-daemon
+if no start or stop function is defined by the service.
+.It Ar command_args
+List of arguments to pass to the daemon when starting.
+.It Ar pidfile
+Pidfile to use for the above defined command.
+.It Ar name
+Display name used for the above defined command.
+.El
+.Sh DEPENDENCIES
+You should define a
+.Ic depend
+function for the service so that
+.Nm
+will start and stop it in the right order in relation to other services.
+As it's a function it can be very flexable, see the example below.
+Here is a list of the functions you can use in a
+.Ic depend
+function. You simply pass the names of the services to it.
+.Bl -tag -width "RC_DEFAULTLEVEL" 
+.It Ic need
+The service will refuse to start until needed services have started and it
+will refuse to stop until any services that need it have stopped.
+.It Ic use
+The service will attempt to start any services we use that have been added
+to the runlevel.
+.It Ic after
+The service will start after thse services and stop before these services.
+.It Ic before
+The service will start before these services and stop after these services.
+.It Ic provide
+We provide this virtual service. For example, named provides dns.
+.It Ic config
+We should recalculate our dependencies if the listed files have changed.
+.It Ic keywords
+Tags a service with a keyword. Currently the only keyword is notimeout
+which means that services do not time out waiting for that service, which only
+applies when services are enabled to start and stop in parallel.
+.El
+.Sh BUILTINS
+.Nm
+defines some builtin functions that you can use inside your service scripts:
+.Bl -tag -width indent
+.It Ic einfo Op Ar string
+Output a green asterisk followed by the string.
+.It Ic ewarn Op Ar string
+Output a yellow asterisk followed by the string.
+.It Ic eerror Op Ar string
+Output a red asterisk followed by the string to stderr.
+.It Ic ebegin Op Ar string
+Same as einfo, but append 3 dots to the end.
+.It Ic eend Ar retval Op Ar string
+If
+.Ar retval
+does not equal 0 then output the string using
+.Ic eerror
+and !! in square brackets
+at the end of the line. Otherwise output ok in square brackets at the end of
+the line. The value of
+.Ar retval
+is returned.
+.It Ic ewend Ar retval Op Ar string
+Same as
+.Ic eend ,
+but use
+.Ic ewarn
+instead of
+.Ic eerror .
+.El
+.Pp
+You can prefix the above commands with the letter
+.Ic v ,
+which means they only
+output when the environment variable
+.Va EINFO_VERBOSE
+is true.
+.Bl -tag -width indent
+.It Ic service_set_value Ar name Ar value
+Saves the
+.Ar name
+.Ar value
+for later retrieval. Saved values are lost when the service stops.
+.It Ic service_get_value Ar name
+Returns the saved value called
+.Ar name .
+.It Ic service_started Op Ar service
+If the service is started, return 0 otherwise 1.
+.It Ic service_starting Op Ar service
+If the service is starting, return 0 otherwise 1.
+.It Ic service_inactive Op Ar service
+If the service is inactive, return 0 otherwise 1.
+.It Ic service_stopping Op Ar service
+If the service is stopping, return 0 otherwise 1.
+.It Ic service_stopped Op Ar service
+If the service is stopped, return 0 otherwise 1.
+.It Ic service_coldplugged Op Ar service
+If the service is coldplugged, return 0 otherwise 1.
+.It Ic service_wasinactive Op Ar service
+If the service was inactive, return 0 otherwise 1.
+.It Xo
+.Ic service_started_daemon
+.Op Ar service
+.Ar daemon
+.Op Ar index
+.Xc
+If the service has started the daemon using
+.Nm start-stop-daemon ,
+return 0 otherwise 1.
+If an index is specified, it has to be the nth daemon started by the service.
+.It Ic mark_service_started Op Ar service
+Mark the service as started.
+.It Ic mark_service_starting Op Ar service
+Mark the service as starting.
+.It Ic mark_service_inactive Op Ar service
+Mark the service as inactive.
+.It Ic mark_service_stopping Op Ar service
+Mark the service as stopping.
+.It Ic mark_service_stopped Op Ar service
+Mark the service as stopped.
+.It Ic mark_service_coldplugged Op Ar service
+Mark the service as coldplugged.
+.It Ic mark_service_wasinactive Op Ar service
+Mark the service as inactive.
+.It Xo
+.Ic checkpath
+.Op Fl d , -directory
+.Op Fl f , -file
+.Op Fl m , -mode Ar mode
+.Op Fl o , owner Ar owner
+.Ar path ...
+.Xc
+Checks to see if the path exists, is of the right type, owned by the right
+people and has the correct access modes. If not, then it corrects the path.
+.El
+.Sh ENVIRONMENT
+.Nm
+sets the following environment variables for use in the service scripts:
+.Bl -tag -width "RC_DEFAULTLEVEL" 
+.It Va SVCNAME
+Name of the service.
+.It Va RC_SOFTLEVEL
+Current runlevel that rc is in.
+.It Va RC_BOOTLEVEL
+Boot runlevel chosen. Default is boot.
+.It Va RC_DEFAULTLEVEL
+Default runlevel chosen. Default is default.
+.It Va RC_SYS
+A special variable to describe the system more.
+Possible values are XENU, XEN0, UML and VPS.
+.It Va RC_UNAME
+The result of `uname -s`.
+.El
+.Sh FILES
+.Pp
+Configuration files, relative to the location of the service.
+If a file ending with .${RC_SOFTLEVEL} exists then we use that instead.
+.Bl -ohang
+.It Pa ../conf.d/${SVCNAME%%.*}
+mulitplexed configuration file.
+Example: if ${SVCNAME} is net.eth1 then look for
+.Pa ../conf.d/net .
+.It Pa ../conf.d/${SVCNAME}
+service configuration file.
+.It Pa /etc/rc.conf
+host configuration file.
+.El
+.Pp
+With the exception of
+.Pa /etc/rc.conf ,
+the configuration files can also influence the dependencies of the service
+through variables. Simply prefix the name of the dependency with rc_.
+Example:
+.Bd -literal -offset indent
+# Whilst most services don't bind to a specific interface, our
+# openvpn configuration requires a specific interface, namely bge0.
+rc_need="net.bge0"
+.Ed

-${HILITE}Dependencies:${NORMAL}
-
-    This is the heart of the OpenRC, as it determines the order
-    in which services gets started, and also to some extend what services
-    get started in the first place.
-
-    The following example demonstrates how to use dependencies in
-    rc-scripts:
-
-    depend() {
-        need foo bar
-        use ray
-    }
-
-    Here we have foo and bar as dependencies of type 'need', and ray of
-    type 'use'.  You can have as many dependencies of each type as needed, as
-    long as there is only one entry for each type, listing all its dependencies
-    on one line only.
-
-    ${GOOD}need${NORMAL}
-      These are all the services needed for this service to start.  If any
-      service in the 'need' line is not started, it will be started even if it
-      is not in the current, or 'boot' runlevel, and then this service will be
-      started.  If any services in the 'need' line fails to start or is
-      missing, this service will never be started.
-
-    ${GOOD}use${NORMAL}
-      This can be seen as representing optional services this service depends on
-      that are not critical for it to start.  For any service in the 'use' line,
-      it must be added to the 'boot' or current runlevel to be considered a
-      valid 'use' dependency.  It can also be used to determine startup order.
-
-    ${GOOD}before${NORMAL}
-      This, together with the 'after' dependency type, can be used to control
-      startup order.  In core, 'before' and 'after' do not denote a dependency,
-      but should be used for order changes that will only be honoured during
-      a change of runlevel.  All services listed will get started *after* the
-      current service.  In other words, this service will get started *before*
-      all listed services.
-
-    ${GOOD}after${NORMAL}
-      All services listed will be started *before* the current service.  Have a
-      look at 'before' for more info.
-
-    ${GOOD}provide${NORMAL}
-      This is not really a dependency type, rather it will enable you to create
-      virtual services.  This is useful if there is more than one version of
-      a specific service type, system loggers or crons for instance.  Just
-      have each system logger provide 'logger', and make all services in need
-      of a system logger depend on 'logger'.  This should make things much more
-      generic.
-
-    ${GOOD}config${NORMAL}
-      This is not really a dependency type, rather it informs the dependency
-      system about config files that may affect the dependencies of the service.
-      One example of this is the netmount service which changes its dependencies
-      depending on the config of /etc/fstab.
-
-    Note that the 'need', 'use', 'before', and 'after' dependency types accept
-    an '*' as an argument.  Having:
-
-    depend() {
-    	before *
-    }
-
-    will make the service start first in the current runlevel, and:
-
-    depend() {
-    	after *
-    }
-
-    will make the service the last to start.
-
-    You should however be careful how you use this, as I really will not
-    recommend using it with the 'need' or 'use' dependency type ... you have
-    been warned!
-
-${HILITE}'net' Dependency and 'net.*' Services:${NORMAL}
-
-    Example:
-
-    depend() {
-        need net
-    }
-
-    This is a special dependency of type 'need'.  It represents a state where
-    a network interface or interfaces besides lo is up and active.  Any service
-    starting with 'net.' will be treated as a part of the 'net' dependency,
-    if:
-
-    1.  It is part of the 'boot' runlevel
-    2.  It is part of the current runlevel
-
-    A few examples are the /etc/init.d/net.eth0 and /etc/init.d/net.lo services.
