"""Imports delicious.com links into Tumblr.

- get all your delicious.com links into a file:

    curl -u user:password \
        'https://api.del.icio.us/v1/posts/all?meta=yes' >links.xml

- if curl is missing:
  open the above URL in a browser and save the resulting page as "links.xml"
- run this script to post the links to Tumblr
- delete your delicious.com account

The link's timestamp, tags and privacy flag are kept.

XML format of a link:

<post description="The problem with Django's Template Tags"
    extended="My reply"
    hash="ec46dd48f9b117f2adc8d7b10b8356d7"
