flpsed is a WYSIWYG PostScript annotator. You can't actually edit existing documents, but you can add arbitrary text lines to existing documents. Added lines can later be re-edited with flpsed. Using pdftops, flpsed can import PDF documents and also add text to them. It is useful for filling in forms, adding notes, etc. In batch mode, it can be used to automate form filling.Changes: flpsed is now based on fltk-1.3.x. PDF files are now detected by their headers instead of the file extension.
