By Claudio Panichi <claudio@roma2.infn.it>

=================================================================

WHAT IS THIS?

This is a very simple plugin that allow a logged-in user to check
it's quota usage on the www server running SquirrelMail.
It's useful just if ( IMAP_SERVER == WWW_SERVER ).
The "quota" binary must be setuid.

CHANGELOG!

  for version 0.5!

- Now disk_quota tries to automatically find the quota-binary if variable
  $quota_binary is not defined by SysAdmin in "option.php"

  partitions!

  to not allow users to use php scripts in their www directory

  page is nicer!
- Use a better english (I hope! Please send me some better dialogs!)

  Physics thesis! =;-)
