## rtftomarkdown.rb
#!/usr/bin/ruby
=begin
Usage: rtftomarkdown.rb FILENAME.rtf

Uses textutil, available on Mac only (installed by default)
Outputs to STDOUT

Notes:

Links are replaced with Markdown references (duplicate links combined).
This works fine on RTF files, but the markup that the Word/textutil
combination produces seems impossible to work with. Most links disappear
when converting from a DOC or DOCX file, and even Word's RTF export is
unworkable.

List levels converted by textutil can not be changed at a given depth.
If you start a second-level nested list as an ordered list, the next
second-level list will be ordered. It's a textutil/RTF thing.
