apt_preferences: need an example

[Abdul Latip <dullatip@angin.com>]

Hello:

Suppose "woody" is the default archive. But, I would like
to use package "xyzzy" from "sid". But, "xyzzy" requires
package "plugh" from "sid" too.

The /etc/apt/sources.list would be like (?):

==============================================================
deb http://blah.blah/debian/ woody main contrib non-free
deb http://blah.blah/debian/ sid main contrib non-free
deb http://blah.blah/debian-non-US/ woody/non-US main contrib non-free
deb http://blah.blah/debian-non-US/ sid/non-US main contrib non-free
deb http://blah.blah/debian-security/ woody/updates main contrib non-free
==============================================================

* May I know, how the /etc/apt/preferences should look like?

* Besides "man apt_preferences", is there any other document
  available?  Could someone please, send me an example of 
  a working /etc/apt/preferences ?

* May I know, how to detect that a new "plugh" is needed by 
  "xyzzy" ?
