+commit 4b3fd94b1cc79c24c4092b6b10ed4627a2648d26
+Author: Guus Sliepen <guus@tinc-vpn.org>
+Date:   Mon Jun 6 16:26:11 2011 +0200
+
+    Improved --logfile option.
+    
+    Instead of UNIX time, the log messages now start with the time in RFC3339
+    format, which human-readable and still easy for the computer to parse and sort.
+    The HUP signal will also cause the log file to be closed and reopened, which is
+    useful when log rotation is used. If there is an error while opening the log
+    file, this is logged to stderr.

+    Nearly tickless tinc.
+    
+    Use pselect instead of select in main_loop (if available). This lets
+    tincd sleeps as long as there is nothing to do.

+
+    Reorder checks for libraries to allow ./configure LDFLAGS=-static.
+    
+    OpenSSL depends on libdl and libz. When linking dynamically, libcrypto will
+    automatically link with the other two libraries.  However, when linking
+    statically, these libraries need to be specified explicitly while linking.  By
+    moving the autoconf checks for libdl and libz before those for libcrypto, we
+    ensure the latter test will be done with the proper libraries.

 The system startup script for tinc, /etc/init.d/tinc, uses the file
 /etc/tinc/nets.boot to find out which networks have to be started.
 
- -- Ivo Timmermans <ivo@debian.org>, Wed, 31 May 2000, 19:56:05 +0200
+Alternatively, you can create a stanza in /etc/network/interfaces, and add a
+line with "tinc-net <netname>". This will cause a tincd to be started which
+uses the configuration from /etc/tinc/<netname>. You can use an inet static
+(with address and netmask options) or inet dhcp stanza, in which case the ifup
+will configure the VPN interface and you do not need to have a tinc-up script.
+
+The following options are also recognized and map directly to the corresponding
+command line options for tincd:
+
+tinc-config <directory>
+tinc-debug <level>
+tinc-mlock yes
+tinc-logfile <filename>
+tinc-chroot yes
+tinc-user <username>
+
+An example stanza:
+
+iface vpn inet static
+	address 192.168.2.42
+	netmask 255.255.0.0
+	tinc-net myvpn
+	tinc-debug 1
+	tinc-mlock yes
+	tinc-user nobody
+
+This will start a tinc daemon that reads its configuration from
+/etc/tinc/myvpn, logs at debug level 1, locks itself in RAM, runs as user
+nobody, and creates a network interface called "vpn". Ifup then sets the
+address and netmask on that interface.
