Dear Lazyweb - Lib Dem benefits policy

[wildeabandon]

Can anyone point me at a the Lib Dem policy on benefits, particularly incapacity benefit? The Tory plans to make the testing more stringent have nixed any plans I might have had to vote for them at the next election, and Labour seem to be going the same way (as well as there being the whole civil liberties problem). This makes the Lib Dems the most likely choice, but after searching through their website I've found a bunch of soundbites, and a paper about helping young people find work, but nothing else more solid, and I'd like to have a bit more of a basis for my decisions.
