How to update Squid and SquidGuard configuration file

[Hilaire Fernandes <cddp40.tice@ac-bordeaux.fr>]

Hello, 

I am looking at building a small .deb package for the skolelinux
project.

This package will just:

1. update the /etc/squid/conf and /etc/squid/squidGuard.conf files with
our prefered setting

2. update nightly the blacklist.

I am wondering how such a .deb package should cleanly update the two
configuration files. Do you have some pointer about that?

Thanks

Hilaire Fernandes
