Scannedonly is a samba VFS module that ensures
that only files that have been scanned for viruses
are visible and accessible to the end user.
Scannedonly was developed because of scalability
problems with samba-vscan. Scannedonly comes in
two parts: a Samba VFS module and (one or more)
daemons. The daemon scans files and marks them
when they are known to be clean. The samba module
simply filters out files that aren't marked clean.
