+Backup Control Scripting
+========================
+
+The script +dupltool+ is a wrapper for duplicity that usually just
+invokes duplicity with all arguents passed on, but every month it
+first makes a stash of the most recent succession of daily snapshots,
+so that the duplicity run at this time is a monthly snapshot.
+
+The script +duplicity-daily+ is a simple control script for daily
+backup that uses configuration from +/etc/duplicity-daily.conf+ that
+defines which backups to make, and from +~/.ssh/config+ as to how to
+connect to the target host (or hosts).
+
+Administration Example
+----------------------
+
+.This is a +/etc/duplicity-daily+ sample
+----
+ENABLED=yes
+OPTIONS=--no-encryption
+TARGET=backup/backup
+/root
+/etc
+/home
+----
+
+The above sample declares backup (without encryption) of directory
+trees +/root+, +/etc+, +/home+ to host +backup+ (as declared in
++~/.ssh/config+) into directories under the user's directory +backup+.
+
+.This is a +~/.ssh/config+ sample
+----
+host backup
+    hostname backup.lan
+    user thishost
+    identityfile ~/.ssh/thishost-backup
+    ServerAliveInterval 15
+    ServerAliveCountMax 4
+    TCPKeepAlive yes
+    RekeyLimit 100M
+    IPQoS reliability
+----
+
+Note that for the above sample, the backup client +root@thishost+ has
+prepared a password-less ssh key to +thishost@backup.lan+ so that
+daily backup can happen without operator intervention.
+
+Debian Package
+--------------
+
+A debian package is built with
+----
+$ make deb
+----
+provided that the build environment is set up, i.e. an ordinary debian
+package building environment.
+
+The package is then installed with
+----
+# dpkg -i ../buckap_<TAB>
+----
+Doing so will install +/usr/bin/dupltool+ and
++/etc/cron.daily/duplicity-daily+, as well as providing an example
++/etc/duplicity-daily.conf+ (incuding rudimentary instructions).
