>  To get a good signal-to-noise ratio (i.e. few false alerts), you need to
  know which files should be checked, and which not (looking at the
  'last modified' timestamp may be helpful, if in doubt).</P
><P
>  To see how to set recursion depths, implement 'check all but xxx' policies
  etc., have a look at <A

>. </P

>  As <SPAN

  it is capable to 'remember' all file system
  changes, thus you won't get bothered twice about the same problem. </P
