      -b           backup original directories before migration

  You can use this script if you're upgrading j-chkmail from a version
  older than 1.11.0 RC3.

  Suggested way to launch this script is with "-b" option : if something
  goes wrong, you can restore initial data from tar files created inside
  /tmp directory

  You shall launch this script just after you compile j-chkmail and just
  before you install the new version.
