r1596: * Remove duplicate packages from DOPACKAGES after argument processing.version_4.1.68

     Closes: #112950
   * dh_compress: deal with links pointing to links pointing to compressed
     files, no matter what order find returns them. Closes: #204169
   * dh_installmodules, dh_installpam, dh_installcron, dh_installinit,
     dh_installogrotate: add --name= option, that can be used to specify
     the name to use for the file(s) installed by these commands. For example,
     dh_installcron --name=foo will install debian/package.foo.cron.daily to
     etc/cron.daily/foo. Closes: #138202, #101003, #68545, #148844
     (Thanks to Thomas Hood for connecting these bug reports.)
   * dh_installinit: deprecated --init-script option in favor of the above.
   * Add dh_installppp. Closes: #43403
