Have students turn in their assignments in Org mode format. From http://www.ocf.berkeley.edu/~rwl/lib/attachments/teaching/100/paper-guidelines.pdf
See sec-2.3 ,---- | I’m going to try an experiment in this course. I would like you to | submit your papers to me as plain text, not in a document format like MS | Word (.doc, .docx), OpenDocument Text (.odt), RTF, or HTML. You are | welcome to useWord, OpenOffice, or another document editor to write your | papers, but please export your paper from these programs as plain text, | formatted according to the guidelines below.1 | | There are several reasons for this. One, I don’t want to require you to | use any particular software to write your papers; you can edit plain | text using a wide variety of programs on any platform. Two, I actually | find the papers in the usual 12 point Times New Roman double-spaced | format pretty difficult to read and work with. By submitting your papers | in plain text, you’re making it easier for me to compile them into a | format that prefer to work with, which means I’ll have more time to | dedicate to giving you helpful feedback. | | In case you’re wondering: these guidelines are a subset of the | formatting rules of Org mode for GNU Emacs (http://orgmode.org). I’m | going to use Org mode to compile your papers using the LATEX | typesetting system. If you want, you can use any formatting compatible | with Org mode, but you’re not required to learn it. `----
