It is non-trivial to implement support for more than one PLT, because
of dependecies between applications.

Therefore Dialyzer only uses a single PLT.

We don't want to have the PLT inside OTP itself (as it was earlier),
because that causes problems if OTP is installed in a read-only
file-system or in Clearcase.

However, we might somehow provide a pre-built PLT that you copy to your
home directory to get started quickly.
