Physics of Anti-Sway bars

[Awgertoo@aol.com]

My understanding is adding a front antisway bar or increasing the size of an 
existing one  decreases front body lean, induces understeer and makes the 
front push out in a turn, and that adding a rear antisway bar, etc. etc. 
induces 
oversteer, etc.

Can someone explain if this is correct and the physics/handling theory 
involved?
