+For the main event loop, tinc uses the libevent library.
+
+If this library is not installed, you wil get an error when configuring
+tinc for build.
+
+You can use your operating system's package manager to install this if
+available. Make sure you install the development AND runtime versions
+of this package.
+
+If you have to install libevent manually, you can get the source code
+from @url{http://monkey.org/~provos/libevent/}. Instructions on how to configure,
+build and install this package are included within the package. Please
+make sure you build development and runtime libraries (which is the
+default).

you can easily create a public/private keypair by entering the following command:
@example
-tincd -n @var{netname} -K
+tincctl -n @var{netname} generate-keys
@end example
Tinc will generate a public and a private key and ask you where to put them.
A, B, C and D all have generated a public/private keypair with the following command:
@example
-tincd -n company -K
+tincctl -n company generate-keys
@end example
The private key is stored in @file{@value{sysconfdir}/tinc/company/rsa_key.priv},
Set debug level to @var{level}. The higher the debug level, the more gets
logged. Everything goes via syslog.
-@item -k, --kill[=@var{signal}]
-Attempt to kill a running tincd (optionally with the specified @var{signal} instead of SIGTERM) and exit.
-Use it in conjunction with the -n option to make sure you kill the right tinc daemon.
-Under native Windows the optional argument is ignored,
-the service will always be stopped and removed.
-
@item -n, --net=@var{netname}
Use configuration for net @var{netname}. @xref{Multiple networks}.
-@item -K, --generate-keys[=@var{bits}]
-Generate public/private keypair of @var{bits} length. If @var{bits} is not specified,
-1024 is the default. tinc will ask where you want to store the files,
-but will default to the configuration directory (you can use the -c or -n option
-in combination with -K). After that, tinc will quit.
+@item --controlsocket=@var{filename}
+Open control socket at @var{filename}. If unspecified, the default is
+@file{@value{localstatedir}/run/tinc.@var{netname}.control}.
@item -L, --mlock
Lock tinc into main memory.
Write log entries to a file instead of to the system logging facility.
If @var{file} is omitted, the default is @file{@value{localstatedir}/log/tinc.@var{netname}.log}.
-@item --pidfile=@var{file}
-Write PID to @var{file} instead of @file{@value{localstatedir}/run/tinc.@var{netname}.pid}.
-
@item --bypass-security
Disables encryption and authentication.
Only useful for debugging.
Temporarily increases debug level to 5.
Send this signal again to revert to the original level.
-@item USR1
-Dumps the connection list to syslog.
-
-@item USR2
-Dumps virtual network device statistics, all known nodes, edges and subnets to syslog.
-
-@item WINCH
-Purges all information remembered about unreachable nodes.
