Behaviors on CakePHP 1.1

I have used cakePHP 1.2 and know how to use behaviors in it.

using cakephp 1.1 on a new project(i know it might sound silly but the project is very similar to an older project we have which was built on 1.1).

after a little googling i have come to believe that cakephp 1.1 models did not have behaviors.
cannot find any reference in the manual as well.

is there a way around this? would be nice to have the containable behavior.

Cheers
