       deb-prerm - package pre-removal maintainer script

SYNOPSIS
       prerm

DESCRIPTION
       A  package  can  perform  several  pre-removal  actions  via maintainer

       The script can be called in the following ways:

       prerm remove
              Before the package is removed.

       old-prerm upgrade new-version
              Before an upgrade.

       new-prerm failed-upgrade old-version new-version
              If the above upgrade fails.

       prerm deconfigure in-favour new-package new-version
           [ removing old-package old-version ]
              Before  package is deconfigured while dependency is replaced due
              to conflict.

       prerm remove in-favour new-package new-version
              Before the package is replaced due to conflict.
