I wrote a program for assisting a student writing a research paper. It took 5 years and still could use some work. It involves adding highlights to websites and computer files, dragging the highlights to the outliner part or the program, adding comments and summaries to each highlight (making it a Note), organizing these Notes within an outline for the paper, so then the user could write each section of the outline while referring to the appropriate notes and original sources. That's 5 years and 13,000 lines at about 11 lines a work day. That doesn't seem like much, but historically programmer productivity has been about 10 lines a day. Some people do dispute 10 lines a day, but it fits my experience. Big projects take lots of time.
