 #!/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.
