# Google Reader to Evernote

# Quick hack together of a Ruby script which will pull all your Google Reader
# starred items into an Evernote notebook in ENML (Evernote export format).
# Requires Ruby 2.0, no other special dependencies. Should work on 1.9 but I 
# haven't tested it.
#
# Get your Google Reader data from 
#   https://www.google.com/takeout/#custom:reader
# Unpack the zip file, find starred.json, feed it to this supplying an output
# filename.
#
# Should preserve item title, the canonical URL, the date it was starred, 
# and the clipped content in HTML format. Worked for my 986 starred items,
# hope it works for yours.
#
# I didn't use tags or categories with starred items, so I haven't
# attempted to handle those. Improvements and bug fixes welcomed.
