The Luggage allows you to automate the process of creating Apple Installer packages in the .pkg format. It does so by leveraging the automation power of the “make” utility — actually, GNU Make — which is installed on Mac OS X systems by way of Apple’s Xcode developer tools.
The packaging mode of the Luggage takes your source files, places them in a specially-prepared temporary location, and builds an installer package from that. All of these steps would be more tedious and error-prone without the automation steps that are taken care of for you if you use the Luggage.
In its second mode, the Luggage can take the process one step further to wrap your brand-new installer in a disk image.
Once you have the Luggage set up for your installer project, both of these modes are just one command away.
If any of this is of interest to you — particuarly if you have to create or maintain lots of software installers or you need to rebuild your installers frequently — then read on, because learning the Luggage can save you time and energy.
