[BlueBream] last question: bluebream vs. django

[Ilshad Khabibullin]

Hi, here are short instruction for ZEO quick start :)

Setup ZEO server:

$ mkdir zeoserver
$ cd zeoserver

Take buildout.cfg template here: http://gist.github.com/366185

(or $ wget
http://gist.github.com/raw/366185/1e8011c63b3ba2d617edf0b98be5ac3f7eec8392/zeoserver-buildout.cfg-O
buildout.cfg)

Take bootstrap.py:

$ wget http://python-distribute.org/bootstrap.py

Edit buildout.cfg. Notice the name of filestorage (in the template - `foo`)
- ZEO client will seek at ZEO server by this name (ZEO server can serve
number of databases.) See more info in documention of zeo package and
zc.zodbrecipes package.

Build and run the ZEO server:

$ python bootstrap.py
$ bin/buildout
$ bin/server start

Other options:

$ bin/server stop
$ bin/server status

See other scripts in bin/ directory.

Next, make you BlueBream project be a ZEO client:. For this, change
zope.conf like this:
http://github.com/astoon/bbru/blob/master/etc/zeo.conf(edit, notice
the name of the storage).

That's it, basically.
