I've implemented --get-selections and --set-selections in dpkg 1.3.9
which will be released some time this weekend.

--get-selections produces a list of lines each with a package name and
wanted state.  By default it lists all the packages; you can specify
package names or patterns too.

--set-selections reads such a list and updates the wanted state for
each one in it.

You can do what `dpkg --select <package>' would do with
`echo <package> install | dpkg --set-selections'.

Ian.
