PDF, editing
From FreeBSDwiki
Here is a trick which I read about the other day. If you want to edit a PDF you can use KWord. It works pretty well, just open up KWord and open up a PDF and it will convert about 90% of it. All the text is aligned pretty accuratly and it imports all the pictures in the file as well.
Then you can use KWord to edit and Print back out to a PDF.
