I have code that used to do it at

    http://barzilay.org/misc/wxme-to-text

Last time I used it was a while ago, so it might need some refreshing,
but it looks like it works fine with a few things that I tried.  It
does lose information like images and nice drracket fractions, but
it's fine if you just want a quick overview of the code.

For future homeworks, you can make the handin server create such
textual versions of submissions, so you don't need this separate
process.  It's based on similar code, so suffers from the same issues
-- so if you want plain text files that you can also run, you can set
it to reject submissions that have things that cannot be converted to
plain text.  (But for an htdp course you probably don't want that.)
