TODO
****

- more testing, esp. in a production environment
- improve and extend documentation
- write VFS modules for more virusscanners
- for speed reasons, scan only a file (again) if its checksum 
  does not match the stored checksum (i.e. the file has been changed)
- move infected file into quarantine directory (optional)
- scan files after they have been copied to a share and move them then
  into quaratine directory, probably using the veto files feature of
  Samba, too (optional)
- provide the possibilty to run a script if a virus is found (i.e.
  to generate an alert mail via script)
- some virus scanners report suspicious files or intented "viruses", which
  are currently not blocked. If they are blocked or not should be configurable
  via the config file mentioned above
- ship with configure script (i.e. to detect if popt lib is installed or not)
  [mainly for Samba >=2.2.5]
- Windows opens file(s) several times, if i.e. a directory is opened in
  Explorer or being double-clicked. Need a good mechanism to dected this
  and avoid scanning of the same file several times in a very short period
  of time.
- some re-structuring of the code / general code clean-up / security
  code audit
