Create installation setup (package)

[mourad]

Hello everyone, I want to create a package for application with PackageManager and using script postinstall but I've encoutered some problems.
I've 2 packages and 2 files to copy after installation. First I want to install the Database firebird, after I want to copy the 2 files into a default location and finally I want to lunch the package for installing my application.
Can anyone tell me how to do. I've tried it with package manager but I was not able to use scripts. I'm on Mac OS X 10.4 Tiger
Best regards,
Mourad.
