Forget all of those magical command-line PDF incantations and edit
your PDFs easily with Xournal.
Somehow, despite all the issues with proprietary clients and the history of
security issues with Acrobat, PDFs have become the de facto standard for your
average print-ready document shared around the office. Sure, people might use
some kind of open document format or a cloud editor if they intend to edit a
document, but if the goal is to print the document or lock its
contents in place, most people these days will export it to a PDF.
