2005-08-08: atool 0.31.0 released.
  ATTENTION: This release fixes a serious bug which might cause files and
  directories to be removed in some circumstances when using adiff. I
  recommend upgrading to the 0.31.0 immediately. If you cannot upgrade, you
  are safe as long as you do not use the adiff command on untrusted
  archives.
  Here are the details: Symbolic links would be followed when temporary
  directories were removed recursively. Only the adiff command removed
  directories in this way - the extracted files of the archives it
  compared. This means that if you ran adiff on an archive containing a
  symbolic link that pointed to, say, /foo, /foo would be removed
  recursively! This was due to a missing check for symbolic links. This bug
  was found by code auditing, and has been fixed in this release.

  disabled, also suggested by Meino Christian Cramer).
