pdfcomments extracts comments from a PDF and puts them in a text file. It is most useful for turning text comments and sticky notes into a list of comments with page numbers.

By default all comments are minor. You can specify a major comment by adding an asterisk at its beginning.

Say you have test.pdf and you add the following comments with Acrobat Reader, PDFExpert, or your annotation tool of choice:

• page 1: a text comment, Text is unclear.
• page 2: a sticky note, Sticky note.
• page 2: a text comment, * Important comment.

Run pdfcomments test.pdf and it will produce the following output file:

Major comments:

p2: Important comment.

Minor comments:

p1: Text is unclear.
p2: Sticky note.
