New release on http://fex.rus.uni-stuttgart.de/fex.html
                                                           
Important changes:

- security enhancement: the variable $admin_pw has moved from fex.ph to
  auth-ID $spooldir/$admin/@ 

- fac (CGI) uses auth-ID of admin user for login and has a logout feature

- fac -P makes an user persistent (no account expiration)

- fac -E shows examples

- fex_cleanup does not terminate any more on errors, this prevents dangling
  spool files
  
- reenabled IPv6 support, see doc/IPv6 for details
