How does one set a background image in an OSX .pkg?

Question

I am creating a .pkg installer for my OSX application and I am having trouble figuring out how to set the background image.

I am creating my installer in my build script like this:

pkgbuild --root $APP_FOLDER --identifier "com.company.product" $FINAL_PKG

This works great but I have not been able to find any information about setting the background image in the man pages. I have seen package installers that have custom background images, how does one set it?

EDIT:

Here is a screenshot of a package installer with a custom background:

Answer 1

Ah ha! There is a resources flag that goes along with productbuild. Here is a stackoverflow question addressing the resources: How do I build an OS X installer package with a custom background with productbuild?

It mentions --resources /path/Resources

and an en.lproj subdirectory, and an XML resources file. You can specify the background.jpg or modify an existing one.

Hope this points you in the right direction(s).

Answer 2

This was most likely done with a tool apple had for creating installers.

You might be able to find it if you search for it on the OS X developer site of Apple

NOTE:

I don't think an installer is the best solution! Making your app in a way that frees you from an installer is not hard. License Agreement, Pre- and Post script functions can be coded in-app.
