We’re now offering a free trial version of Everport that can be downloaded from infinitenil.com. The free trial is not time limited. It simply only lets you import one Backpack page at a time. That way you can try it out and see how it works for you.
Then you can either click away and select a page and then import, say 100 times, or save yourself a boatload of time and purchase the full version at the Mac App Store.
