# Rake tasks for building a jekyll blog and deploying to S3.
#
# These tasks aren't intended to replace the `jekyll` executable,
# but provide convenient Rake-isms to generate the destination dir
# when necessary.
#
# To write to s3, it assumes there is a bucket field in the
# jekyll config:
#     aws:
#       bucket: 'my-s3-bucket'

/**
 *
 * HTMLElement.replicate()
 *
 * Here's an extension to the DOM's [HTMLElement interface][1] that completely
 * replicates an element. Unlike `Node.cloneNode`, this method also copies over
 * relevant styles. This allows you to clone nodes completely detached from the
 * source document, but with enough information to render their independent
 * representation.
