Another Dselect cockup 2

[Paul <paul.walton@dial.pipex.com>]

I`m sending this again as nobody posted a reply last time. Sorry if it`s
a stupid question but I`m still stumped, and I`ve read and reread the
help pages.

By a combination of wild keystrokes I seem to have asked Dselect to
remove a number of required packages, my problem is that I can`t seem to
find out how to reset it so that it just displays the current situation
with nothing to install or remove. I would imagine that this is possible
but I can`t find the answer.

Thanks in advance

Paul
