It just unregisters libraries not delete them actually. But I guess it
is enough for you.

The "cabal-delete" command does delete libraries and I'm planning to
integrate "cab" and "cabal-delete". But the author of "cabal-delete"
is now suffering from the Tsunami in Japan. I'm just waiting for
his recovery.

I want to integrate "cab" and "cabal-dev" also. But I cannot
understand how to use "cabal-dev" at this momemnt...

Have you read this?

cabal-dev is a wrapper around cabal.  It creates the directory "cabal-dev" in your current directory when you run commands.

If you understand how to use 'cabal' then 'cabal-dev' should be pretty easy to figure out.  Do you have any specific questions?
