Importing ReadItLater HTML into Readability via email
#
# this requires the nokogiri and mail gems
# this requires a sendgrid account, since you don't want to deal
# with setting up smtp delivery on your own machine
# sendgrid gives you 200 emails/day free
#
# 1. export from readitlater
# 2. separate the Unread and Archive sections (this doesn't distinguish URLs)
# 3. configure SMTP and email destination
# 4. go
