+openresolv is a resolvconf implementation which manages resolv.conf
+You can find the latest version at http://roy.marples.name/projects/openresolv
+It is written and maintained by Roy Marples <roy@marples.name>
+
+This resolvconf implementation, along with its subscribers, work with a
+POSIX compliant shell and userland utilities. It is designed to work without
+tools such as sed as it *has* to work without /usr being available.
+
+On systems where resolvconf is expected to be used before /var/run is available
+for writing, you can configure openresolv to write somewhere else, like say a
+ramdisk.

+.Os
+.Sh NAME
+.Nm resolvconf
+.Nd a framework for managing multiple DNS configurations
+.Sh SYNOPSIS
+.Nm
+.Fl I
+.Nm
+.Op Fl m Ar metric
+.Op Fl p
+.Fl a Ar interface No < Ns Pa file
+.Nm
+.Op Fl f
+.Fl d Ar interface
+.Nm
+.Fl il Ar pattern
+.Nm
+.Fl u
+.Sh DESCRIPTION
+.Nm
+manages
+.Xr resolv.conf 5
+files from multiple sources, such as DHCP and VPN clients.
+Traditionally, the host runs just one client and that updates
+.Pa /etc/resolv.conf .
+More modern systems frequently have wired and wireless interfaces and there is
+no guarantee both are on the same network.
+With the advent of VPN and other
+types of networking daemons, many things now contend for the contents of
+.Pa /etc/resolv.conf .
+.Pp
+.Nm
+solves this by letting the daemon send their
+.Xr resolv.conf 5
+file to
+.Nm
+via
+.Xr stdin 3
+with the argument
+.Fl a Ar interface
+instead of the filesystem.
+.Nm
+then updates
+.Pa /etc/resolv.conf
+as it thinks best.
+When a local resolver other than libc is installed, such as
+.Xr dnsmasq 8
+or
+.Xr named 8 ,
+then
+.Nm
+will supply files that the resolver should be configured to include.
+.Pp
+.Nm
+can mark an interfaces
+.Pa resolv.conf
+as private.
+This means that the name servers listed in that
+.Pa resolv.conf
+are only used for queries against the domain/search listed in the same file.
+This only works when a local resolver other than libc is installed. 
+See
+.Xr resolvconf.conf 5
+for how to configure
+.Nm
+to use a local name server.
+.Pp
+When an interface goes down, it should then call
+.Nm
+with
+.Fl d Ar interface
+arguments to delete the
+.Pa resolv.conf
+file for the
+.Ar interface .
+.Pp
+Here are some more options that
+.Nm
+has:-
+.Bl -tag -width indent
+.It Fl I
+Initialise the state directory
+.Pa @VARDIR@ .
+This only needs to be called if the initial system boot sequence does not
+automatically clean it out; for example the state directory is moved
+somewhere other than
+.Pa /var/run .
+If used, it should only be called once as early in the system boot sequence
+as possible and before
+.Nm
+is used to add interfaces.
+.It Fl f
+Ignore non existant interfaces.
+Only really useful for deleting interfaces.
+.It Fl i Ar pattern
+List the interfaces, optionally matching
+.Ar pattern ,
+we have
+.Pa resolv.conf
+files for.
+.It Fl l Ar pattern
+List the
+.Pa resolv.conf
+files we have.
+If
+.Ar pattern
+is specified then we list the files for the interfaces that match it.
+.It Fl m Ar metric
+Set the metric of the interface when adding it, default of 0.
+Lower metrics take precedence.
+This affects the default order of interfaces when listed.
+.It Fl p
+Marks the interface
+.Pa resolv.conf
+as private.
+.It Fl u
+Force
+.Nm
+to update all it's subscribers.
+.Nm
+does not update the subscribers when adding a resolv.conf that matches
+what it already has for that interface.
+.El
+.Pp
+.Nm
+also has some options designed to be used by it's subscribers:-
+.Bl -tag -width indent
+.It Fl v
+Echo variables DOMAINS, SEARCH and NAMESERVERS so that the subscriber can
+configure the resolver easily.
+.El
+.Sh INTERFACE ORDERING
+For
+.Nm
+to work effectively, it has to process the resolv.confs for the interfaces
+in the correct order.
+.Nm
+first processes interfaces from the
+.Sy interface_order
+list, then interfaces without a metic and that match the
+.Sy dynamic_order
+list, then interfaces with a metric in order and finally the rest in
+the operating systems lexical order.
+See
+.Xr resolvconf.conf 5
+for details on these lists.
+.Sh IMPLEMENTATION NOTES
+If a subscriber has the executable bit then it is executed otherwise it is
+assumed to be a shell script and sourced into the current environment in a
+subshell.
+This is done so that subscribers can remain fast, but are also not limited
+to the shell language.
+.Pp
+Portable subscribers should not use anything outside of
+.Pa /bin
+and
+.Pa /sbin
+because
+.Pa /usr
+and others may not be available when booting.
+Also, it would be unwise to assume any shell specific features.
+.Sh ENVIRONMENT
+.Bl -ohang
+.It Va IF_METRIC
+If the
+.Fl m
+option is not present then we use
+.Va IF_METRIC
+for the metric.
+.It Va IF_PRIVATE
+Marks the interface
+.Pa resolv.conf
+as private.
+.El
+.Sh FILES
+.Bl -ohang
+.It Pa @SYSCONFDIR@/resolvconf.conf
+Configuration file for
+.Nm .
+.It Pa @LIBEXECDIR@
+Directory of subscribers which are run every time
+.Nm
+adds, deletes or updates.
+.It Pa @LIBEXECDIR@/libc.d
+Directory of subscribers which are run after the libc subscriber is run.
+.It Pa @VARDIR@
+State directory for
+.Nm .
+.El
+.Sh HISTORY
+This implementation of
+.Nm
+is called openresolv and is fully command line compatible with Debian's
+resolvconf, as written by Thomas Hood.
+.Sh BUGS
+.Nm
+does not validate any of the files given to it.
+.Pp
+When running a local resolver other than libc, you will need to configure it
+to include files that
+.Nm
+will generate.
+You should consult
+.Xr resolvconf.conf 5
+for instructions on how to configure your resolver.

+.Sh NAME
+.Nm resolvconf.conf
+.Nd resolvconf configuration file
+.Sh DESCRIPTION
+.Nm
+is the configuration file for
+.Xr resolvconf 8 .
+The
+.Nm
+file is a shell script that is sourced by
+.Xr resolvconf 8 ,
+meaning that
+.Nm
+must contain valid shell commands.
+Listed below are the standard
+.Nm
+variables that may be set.
+.Pp
+After updaing this file, you may wish to run
+.Nm resolvconf -u
+to apply the new configuration.
+.Sh RESOLVCONF OPTIONS
+.Bl -tag -width indent
+.It Sy interface_order
+These interfaces will always be processed first.
+If unset, defaults to the following:-
+.D1 lo lo[0-9]*
+.It Sy dynamic_order
+These interfaces will be processed next, unless they have a metric.
+If unset, defaults to the following:-
+.D1 tap[0-9]* tun[0-9]* vpn vpn[0-9]* ppp[0-9]* ippp[0-9]*
+.It Sy search_domains
+Prepend search domains to the dynamically generated list.
+.It Sy search_domains_append
+Append search domains to the dynamically generated list.
+.It Sy name_servers
+Prepend name servers to the dynamically generated list.
+You should set this to 127.0.0.1 if you use a local name server other than
+libc.
+.It Sy name_servers_append
+Append name servers to the dynamically generated list.
+.It Sy private_interfaces
+These interfaces name servers will only be queried for the domains listed
+in their resolv.conf.
+Useful for VPN domains.
+This is equivalent to the
+.Nm resolvconf -p
+option.
+.It Sy state_dir
+Override the default state directory of
+.Pa @VARDIR@ .
+This should not be changed once
+.Nm resolvconf
+is in use unless the old directory is copied to the new one.
+.El
+.Sh LIBC OPTIONS
+The following variables affect
+.Xr resolv.conf 5
+directly:-
+.Bl -tag -width indent
+.It Sy resolv_conf
+Defaults to
+.Pa /etc/resolv.conf
+if not set.
+.It Sy resolv_conf_options
+A list of libc resolver options, as specified in
+.Xr resolv.conf 5 .
+.It Sy resolv_conf_passthrough
+When set to YES the latest resolv.conf is written to
+.Sy resolv_conf
+without any alteration.
+.El
+.Sh SUBSCRIBER OPTIONS
+openresolv ships with subscribers for the name servers
+.Xr dnsmasq 8 ,
+.Xr named 8 ,
+.Xr pdnsd 8
+and
+.Xr unbound 8 .
+Each subscriber can create configuration files which should be included in
+in the subscribers main configuration file.
+.Bl -tag -width indent
+.It Sy dnsmasq_conf
+This file tells dnsmasq which nameservers to use for specific domains.
+.It Sy dnsmasq_resolv
+This file tells dnsmasq which nameservers to use for global lookups.
+.Pp
+Example resolvconf.conf for dnsmasq:
+.D1 nameservers=127.0.0.1
+.D1 dnsmasq_conf=/etc/dnsmasq-conf.conf
+.D1 dnsmasq_resolv=/etc/dnsmasq-resolv.conf
+.Pp
+Example dnsmasq.conf:
+.D1 listen-address=127.0.0.1
+.D1 conf-file=/etc/dnsmasq-conf.conf
+.D1 resolv-file=/etc/dnsmasq-resolv.conf
+.It Sy named_options
+Include this file in the named options block.
+This file tells named which nameservers to use for global lookups.
+.It Sy named_zones
+Include this file in the named global scope, after the options block.
+This file tells named which nameservers to use for specific domains.
+.Pp
+Example resolvconf.conf for named:
+.D1 nameservers=127.0.0.1
+.D1 named_options=/etc/named-options.conf
+.D1 named_zones=/etc/named-zones.conf
+.Pp
+Example named.conf:
+.D1 options {
+.D1 	listen-on { 127.0.0.1; };
+.D1 	include "/etc/named-options.conf";
+.D1 };
+.D1 include "/etc/named-zones.conf";
+.It Sy pdnsd_conf
+This is the main pdnsd configuration file which we modify to add our
+forward domains to.
+If this variable is not set then we rely on the pdnsd configuration file
+setup to read
+.Pa pdnsd_resolv
+as documented below.
+.It Sy pdnsd_resolv
+This file tells pdnsd about global nameservers.
+If this variable is not set then it's written to
+.Pa pdnsd_conf .
+.Pp
+Example resolvconf.conf for pdnsd:
+.D1 nameservers=127.0.0.1
+.D1 pdnsd_conf=/etc/pdnsd.conf
+.D1 # pdnsd_resolv=/etc/pdnsd-resolv.conf
+.Pp
+Example pdnsd.conf:
+.D1 global {
+.D1 	server_ip = 127.0.0.1;
+.D1 	status_ctl = on;
+.D1 }
+.D1 server {
+.D1 	# A server definition is required, even if emtpy.
+.D1 	label="empty";
+.D1 	proxy_only=on;
+.D1 	# file="/etc/pdnsd-resolv.conf";
+.D1 }
+.It Sy unbound_conf
+This file tells unbound about specific and global nameservers.
+.Pp
+Example resolvconf.conf for unbound:
+.D1 nameservers=127.0.0.1
+.D1 unbound_conf=/etc/unbound-resolvconf.conf
+.Pp
