I moved the configurable data from /etc/ppp here, because :

a) I don't want to bloat /etc/ppp with data files, this way it's easier
   to keep an overview. Ok, it's getting more complex this way, so maybe
   it'll be even more difficult to keep an overview, but hey, at least it
   looks tidy this way ;)
   
b) I'm trying to get the config's as far away as possible from the 
   actual scripts, so clueless peoples have less possibilities to mess
   up ;)
   
c) As stated in a) it looks much tidier, especially if dial-in data for
   more then one ISP is required, this way you can have several different
   configs in this directory, and link the configs you want to use to 
   /etc/ppp

   
WHAT'S HERE SO FAR :
-----------------------------------

chap-secrets : 
Links to pap-secrets, as far as I remember both files have format

dialer.* :
These files hold the data needed by chat. chat is the program that diales
your modem. You need to link exactly one of them to /etc/ppp/dialer

dialer.normal :
A general, chat script, which should work for most people (after some minor
adjustments). Authentication is done through the script itself (which is
by the way potentially insecure). Grab yourself minicom, and dial the number
of your ISP, in case you are prompted for login and password, this script 
is the right one for you

dialer.pap :
A general chat script, which should work for most people (after some minor
adjustments). Authentication is done via PAP. Grab yourself minicom and
dial the number of your ISP, if you don't get prompted for anything after
the CONNECT string, this is possibly the thing you need.

dialer.chap :
Well, what shall I say, I haven't written it yet, since I don't have an
account with an ISP using CHAP ;). You know, that you would need this, 
if you are presented CHALLENGE and RESPONSE strings. I think it works very
similar to PAP, so if you get it working with this script, tell me about 
it, and I'll happily include it in the distribution.

pap-secrets :
This file holds your loginkey 

ppp-config.* :
These are the configurationfiles for /etc/ppp/ppp . You need to link 
exactly one of them to /etc/ppp-config

ppp-config.clean :
I consider this file to be a skeleton config for experts use only, since 
it lacks any adjustments and documentation. 

ppp-config.pap :
Use this, if you are using PAP
