We assumed that 'nobody' is running Apache.

First we must create a 'nobody' user in your Interbase Server
(using gsec) and fills preferences at config/config.inc.php3
to setup your web and mail servers.

Secondly, we are going to create our db and setup twig db
configuration:

1) Run where you want to install the database: 
   cd [my database path]
   isql -i [my twig path]/setup/twig.table.ibase
    
   Note:  Database scheme "twig.table.ibase" is given from isql -x,
          so you should edit twig.table.ibase to change the path of
          your .gdb. Uncomment CREATE DATABASE lines.

2) cd [my twig path]/config

3) edit dbconfig.inc.php3
   fills 'nobody' password
   $dbconfig["defaultdb"] = "[my database path]/twig.gdb"
   $dbconfig["sqltype"]   = "ibase"
