NAME
       deb-prerm - package pre-removal maintainer script

SYNOPSIS
       DEBIAN/prerm

DESCRIPTION
       A package can perform several pre-removal actions via maintainer scripts, by including an
       executable prerm file in its control archive (i.e. DEBIAN/prerm during package creation).

       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.

           The new-version is passed only since dpkg 1.18.5.

       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.
