apt-get with both rpm and deb

[belahcene <belahcene@iap-cu.dz>]

Hi every body,
I ve installed SL ( Scientific  Linux)  based on redhat.  It uses  
apt-get for installing package, unfortunatly, it seems don't support deb.
I create sources file like this :

deb 1 sarge main contrib
deb http://172.19.130.161/sarge2 sarge main contrib
deb http://172.19.130.161/sarge3 sarge main contrib
rpm http://172.19.130.161/SL1   apt os

the iso sarge CD 1 is mounted on    http://172.19.130.161/sarge1
the iso sarge CD 2 is mounted on    http://172.19.130.161/sarge2   and 
so on ..

the iso SL CD1 is mounted on    http://172.19.130.161/SL1     .......

from  a debian machine I can install any package  from deb http://.....  
and I have to comment the rpm lines
from  a SL  machine I can install any package  from rpm  http://.....  
and I have to comment the deb lines

Is there a possibility to do both, since  the apt-get install on SL does 
the rpm !!!

thank for help
best  regards
