Here is a first stab at such a UI. I am using debconf as the frontend to it,
which means it can have a variety of looks and feels, including a dialog ui,
like Adam wants. To take a look at it:

* get Mirrors.masterlist out of the CVS for the debian web site (it's in
* apt-get source debconf
* go into debconf/samples, and put aptconf.config and aptconf.templates there.
  Make sure aptconf.config is executable.
* go up one directory and run "make clean test FRONTEND=dialog PACKAGE=aptconf"

It currently handles http and ftp well; cdrom, nfs, and a mounted filesystem
need to be fleshed out. It asks if you want non-free, and if so, if you want
contrib. Then it lets you pick from a list of countries, and choose from a
list of mirrors in the country. It finishes by spitting out an apt.sources
line. There is also provision made for entering mirror data manually.

Using debconf for the frontend might be controversial, but I think it can
handle all the types of prompting we might want to add to this, except
perhaps ordering a list of sources be priority, which I doubt we want to
trouble people with anyway.

One nice features comes to light if you test it with this command:

make clean test FRONTEND=dialog PACKAGE=aptconf PRIORITY=critical

That makes it skip some of the less important questions, which happen to be
those RMS wouldn't like and those I don't think we should trouble a newbie
with. :-)

Template: aptconf/uri_type
Type: select
Choices: cdrom, http, ftp, nfs, filesystem
Default: cdrom
Description: Choose what method apt will use to access the Debian archive
 Apt can access the Debian archive in a variety of ways. Choose the access
 method apt should use. For example if you have a Debian cd, select "cdrom",
 while if you plan to install via a Debian mirror, choose "ftp" or "http".

Template: aptconf/country
Type: select
Choices: ${countries}, enter information manually
Default: US
Description: Select your country
 The first step in choosing what Debian mirror you use is selecting your
 country. If your country is not on this list, select a neighboring
 country. The goal is to find a mirror that is close to you on the network.
 If you want to enter mirror information manually, select the last item on
 the list.

Template: aptconf/mirror
Type: select
Choices: ${mirrors}
Description: Choose the debian mirror to use
 Select the debian mirror apt should use. You should select a mirror that
 is close to you on the net.

Template: aptconf/hostname
Type: string
Description: Enter mirror hostname
 Enter the hostname of the mirror you want to use.

Template: aptconf/directory
Type: string
Default: /debian
Description: Enter mirror directory
 Enter the directory the mirror is located in.

Template: aptconf/non-free
Type: boolean
Default: false
Description: Use non-free software?
 Debian makes available some non-free software. though this software is not
 part of Debian proper, it can be installed with apt. This software has
 limitations on its distribution, modification, and/or use. Do you wish to
 use this software?

Template: aptconf/contrib
Type: boolean
Default: false
Description: Use contrib software?
 Debian includes some software that, while free, does not work without other,
 non-free software. Do you wish to use this software?

Template: aptconf/distribution
Type: select
Choices: stable, unstable
Default: stable
Description: Select Debian distribution to use
 Debian comes in two flavors. Stable is well-tested and rarely changes.
 Unstable is untested and frequently changing. Which of the two do you wish
 to install?
