This script assigns necessary permissions for the directories that the
webserver writes files to. It also creates the (initially empty) cache 
directories.

Usage $0 user [group] [rights] [list of virtual host domains]

For example, if apache is running as user $AUSER and group $AGROUP (can be found in phpinfo),
 and if you are running as user $USER, type:

  su -c '$0 $USER $AGROUP'
 
This will allow you to delete certain files/directories without becoming root.
  
Or, if you can't become root, but are a member of the group apache runs under
(for example: $AGROUP), you can type:

  $0 $USER $AGROUP

Be aware, that you probably have to do a 

  chown -R $USER *

if your tiki runs in a PHP-safe-mode environment.

If you can't become root, and are not a member of the apache group, but if
your system uses ACL's (check with "mount | grep acl"), then type:

  $0 -acl $USER $AGROUP

If you can't become root, and are not a member of the apache group, and
your system does not support ACL's then type:

  $0 $USER yourgroup 02777

Replace yourgroup with your default group.

NOTE: If you do execute on of the two last commands, you will not be able 
to delete certain files created by apache, and will need to ask your system
administrator to delete them for you if needed.

To use Tiki's multi-site capability (virtual hosts from a single DocumentRoot)
add a list of domains to the command to create all the needed directories.
For example:

  su -c '$0 $USER $AGROUP $RIGHTS domain1 domain2 domain3'

or, if you can't become root:

  $0 $USER $AGROUP 02777 domain1 domain2 domain3

---------
special for mods installer

  $0 $AUSER all

will change perms on all tiki files so you can use the tikimods power.
Remember to run the perms setup again when mods installer use if done.
