Mac installer that runs a script

I need to create an installer for a Mac application that not only unpacks the information开发者_如何转开发 but executes an script before unpacking the information. Also I want an interactive application that asks for some parameters during installation.

Do you know any tool to do that staff?

Thanks!

/Developer/Applications/Utilities/PackageMaker.app

will let you make .pkg installer bundles, these can include pre and post scripts along with files.

If you can't ask for the information you need during the install, consider moving it to the application when it does a first run.
