simple script/runner script to import mephisto comments into disqus
#vim: ruby
#
# This script will import all your Mephisto comments into Disqus (http:/disqus.com)
# parts of it came from http://www.locomotivation.com/blog/2008/12/01/disqus-sinatra-importer.html
# but instead of a blog-engine independent sinatra app we needed a mephisto-specific script that
# will just do the job :)

Thanks for this!

I had to make a few tweaks for the latest rest-client gem and the latest disqus API. You can see those tweaks on this fork: http://gist.github.com/353645
