More real-world objects move to digital. We rarely have to do ordinary paper photos, the number of books sold or released for free in electronic form, becoming popular services storing notes online, and electronic documents are no longer science fiction. For almost every type of content has a cataloger: photos conveniently stored in iPhoto, music in iTunes. Developers from Ironic Software felt that the owners do not have enough poppies convenient program for working with PDF, and a proposed resolution - Yep.
Yep - it's pretty easy cataloger PDF-files. After installation, the application will find all PDF-documents that are stored on your hard disk. The search takes a little time, you may want to limit it to allow "scan" only specific folders
The result is a library of PDF-file, in which the documents have been ordered. Yep there are a few in the sort criteria, the main - it tags (although you can use folders, collections, and "smart" collection). Read the PDF, you can use built-in client, as well as any other reader (eg, Preview).
