How do I tell what version my OS X installers are?

[pepperdotnet]

I have several "Install OS X..." applications that I've downloaded over the years and have on my archive. Unfortunately, when I downloaded them I did not note what the specific version numbers were. How do I find out without actually installing?

For example, I have "Install OS X El Capitan.app" - how do I tell if it is 10.11, 10.11.1, 10.11.2, etc.? Is there a plist somewhere containing the actual OS version number? or do I need to mount the InstallESD.dmg and look for something there?
