NuPagePacker
PagePacker is an impressive little Cocoa application that Aaron Hillegass wrote to assemble PDFs and other documents into small printable booklets. Last month Aaron released the Objective-C source code to PagePacker, and today I'm releasing an equivalent implementation of PagePacker in Nu.
You can download the application from this link: NuPagePacker.dmg. It's a universal binary that includes Nu as a private framework.
See my blog for more details and look for the source on github. Build the shippable disk image with "nuke dmg". Just be sure to have Nu-0.2.4 or later installed when you build it.
