Where to add static routes?

[Sonny Kupka <sonny@nothnbut.net>]

I'm switching from Slackware to Debian and I'm a little lost ;)

In Slackware I loaded my routes to /etc/rc.d/rc.inet1 like:

route add -net xxx.xxx.xxx.xxx gw xxx.xxx.xxx.xxx netmask 255.255.255.240

I tried to put that line in my /etc/network/interfaces file just after it 
started the eth0, but that didn't work right..

Another thing.. What the equivalent of an /etc/rc.d/rc.local

Thanks for any pointers you may have ...
