+= NuWa Slave : automated build/test setup =
+
+Running a slave provides :
+  * automatically updated and tested dybinst'allation
+  * web interface to the status of the installation including history of build/test status
+
+= How to setup a slave =
+
+== Pre-requisites : python 2.5?, setuptools, bitten ( 0.6dev-r561 ) ==
+
+Although bitten is installed by dybinst into nuwa python as part of the nosebit external, 
+it is more logical to install this into your system python as the slave 
+can then perform ''green-field'' dybinst builds without recourse to existing dybinst-allations. 
+{{{
+svn checkout http://svn.edgewall.org/repos/bitten/branches/experimental/trac-0.11@561 bitn
+cd bitn
+python setup.py develop       ## probably with sudo
+}}}
+  * more recent revisions of bitten have incompatibilites with the trac 0.11 master 
+
+
+== Interactive Test Running of the slave ==
+
+  * Verify that '''bitten-slave''' is installed and in your PATH and is the expected ''standard'' version 
+{{{
+[blyth@belle7 ~]$ which bitten-slave
+/usr/bin/bitten-slave
+[blyth@belle7 ~]$ bitten-slave --version
+bitten-slave 0.6dev-r561
+}}}
+
+  * export dybinst into directory to be used for slave builds (you could use an existing dybinst-allation also) 
+  * interactive test run of the slave
+{{{
+./dybinst trunk slave 
+}}}
+     * this should fail complaining of lack of config in your {{{$HOME/.dybinstrc}}}
+
+  * add or create {{{$HOME/.dybinstrc}}} containing connection credentials
+{{{
+slv_buildsurl=http://dayabay.ihep.ac.cn/tracs/dybsvn/builds
+slv_username=slave
+slv_password=***
+slv_loghost=http://your.address       ## if you are able to publish logfiles 
+}}}
+
+
+If your credentials are correct the expected startup messages are :
+{{{
+[blyth@cms01 trunk]$ ./dybinst trunk slave
+Updating existing installation directory installation/trunk/dybinst.
+Updating existing installation directory installation/trunk/dybtest.

+[DEBUG   ] Sending POST request to 'http://dayabay.ihep.ac.cn/tracs/dybsvn/builds'
+[INFO    ] No pending builds
+}}} 
+
+
+Note that slave asked the master if there are any builds to do and got reply  '''No pending builds''' , the default config is to 
+ask the master every 5 mins if there is anything to do.
+
+
+In order for the master to instruct the slave to perform builds you must send the '''hostname''' to Simon :
+{{{
+[blyth@belle7 ~]$ hostname
+belle7.nuu.edu.tw
+}}}
+who will inform add the slave to the master through the Trac Admin web interface.
+
+
+
+== Running the slave continuously ==
+
+Supervisord is recommended to keep the slave running, 
+  * http://supervisord.org/
+
+Install supervisord into your system python with easy_install or pip :
+{{{
+easy_install supervisor
+}}}
+
+For tips on using supervisord, see :
+  * http://dayabay.phys.ntu.edu.tw/tracs/env/browser/trunk/base/sv.bash
+     * ( includes functions to setup redhat init.d scripts that restart supervisord and all its children when your machine is rebooted ) 
+
+An example of the supervisord config used to keep the dybslv running :
