debconf-copydb copies items from an existing debconf database into another, possibly new database. The
       two databases may have different formats; if so a conversion will automatically be done.

         debconf-copydb configdb backup

       Copy all of configdb to backup, assuming you already have the backup database defined in debconf.conf.

         debconf-copydb configdb newdb --pattern='^slrn/' \
               --config=Name:newdb --config=Driver:File \
               --config=Filename:newdb.dat

       Copy  slrn's  data  out of configdb, and into newdb. newdb is not defined in the rc file, so the --config
       switches set up the database on the fly.

         debconf-copydb configdb stdout -c Name:stdout -c Driver:Pipe \
               -c InFd:none --pattern='^foo/'

       Spit out all the items in the debconf database related to package foo.

         debconf-copydb configdb pipe --config=Name:pipe \
                       --config=Driver:Pipe --config=InFd:none | \
               ssh remotehost debconf-copydb pipe configdb \
                       --config=Name:pipe --config=Driver:Pipe

       This uses the special purpose pipe driver to copy a database to a remote system.

sourcedb
           The  name  of  the source database. Typically it will be defined in your debconf.conf (or .debconfrc)
           file.

       destdb
           The name of the destination database. It may be defined in debconf.conf or .debconfrc, or  you  might
           define it on the command line (see below).

       -ppattern, --patternpattern
           If this is specified, only items in sourcedb whose names match the pattern will be copied.

       --owner-patternpattern
           If this is specified, only items in sourcedb whose owners match the pattern will be copied.

       -cfoo:bar, --configFoo:bar
           Set option Foo to bar. This is similar to writing:

             Foo: bar

           In  debconf.conf,  except  you probably want to leave off the space on the command line (or quote it:
           "Foo: bar"). Generally must be used multiple times, to build up a full  configuration  stanza.  While
           blank lines are used to separate stanzas in debconf.conf, this program will assume that "Name:dbname"
           denotes the beginning of a new stanza.
