MSBuild task for Web Deployment?

Hi;

Is there a task for this (none in the MSDN docs). If not, I found "msbuild MyWeb.sln /p:Configuration=Release" suggested on the msdn website - but how do I know if this will generate the merged website?

I've also noticed that the directory PrecompiledWeb is not created if I run my Web Deployment project directly within VS 2005 but it is created if I do the above.

thanks - dave
