How to install Drupal development environment.

So, up to now, there is a drupal core exported via NFS to the development server. Now we set up a new development project, adding specific modules and themes to the /sites directory. The /sites/all will contain all the standard modules, like CCK, Views, Mollom, Pathauto, which are used in every project. The project stuff (/sites/project-1.com, /sites/nw-cee.com and /sites/wepoca.net) will be set up and exported to the development server separately. The /sites directory will look like this:

defaults
all
- modules
- themes
- default.setting.php
project-1.com
- modules
- themes
- files
- setting.php
nw-cee.com
- modules
- themes
- files
- setting.php
wepoca.net
- modules
- themes
- files
- setting.php
