Migrate your blogger blog posts to jekyll.

blogspot_to_jekyll.rb

# Short overview:
# 1) Fetch blogger feed
# 2) For each post in feed
#    1) create a file with name `YYYY-MM-DD-post-title.markdown`, with
#       the following structure:
#
#       ---
#       layout: post
#       title: `post-title`
#       date: 2011-07-30 10:44
#       comments: true
#       categories: 
#       ---
#
#       #{blog_post_content_in_markdown_format}
# 3) Write each file to a directory `_posts`
