+On Windows (not Cygwin), the scripts should have the extension
+.Pa .bat .
+.Bl -tag -width indent
+.It Pa @sysconfdir@/tinc/ Ns Ar NETNAME Ns Pa /tinc-up
+This is the most important script.
+If it is present it will be executed right after the tinc daemon has been started and has connected to the virtual network device.
+It should be used to set up the corresponding network interface,
+but can also be used to start other things.
+Under Windows you can use the Network Connections control panel instead of creating this script.
+.It Pa @sysconfdir@/tinc/ Ns Ar NETNAME Ns Pa /tinc-down
+This script is started right before the tinc daemon quits.

make sure you have read this entire section so you know what to expect.

which will assign a netname to this daemon.
The effect of this is that the daemon will set its configuration
-``root'' to @value{sysconfdir}/tinc/@emph{netname}/, where @emph{netname} is your argument to the -n
-option. You'll notice that it appears in syslog as ``tinc.@emph{netname}''.
+``root'' to @value{sysconfdir}/tinc/@var{netname}/, where @var{netname} is your argument to the -n
+option. You'll notice that it appears in syslog as ``tinc.@var{netname}''.
However, it is not strictly necessary that you call tinc with the -n
option. In this case, the network name would just be empty, and it will
be used as such. tinc now looks for files in @value{sysconfdir}/tinc/, instead of
-@value{sysconfdir}/tinc/@emph{netname}/; the configuration file should be @value{sysconfdir}/tinc/tinc.conf,
+@value{sysconfdir}/tinc/@var{netname}/; the configuration file should be @value{sysconfdir}/tinc/tinc.conf,
and the host configuration files are now expected to be in @value{sysconfdir}/tinc/hosts/.
But it is highly recommended that you use this feature of tinc, because
