# DocumentFragment. This is different from most filters in that it can take a
# non-HTML as input. It must be used as the first filter in a pipeline.

# Context options:
# :gfm => false Disable GFM line-end processing
# :commonmarker_extensions => [ :table, :strikethrough,
# :tagfilter, :autolink ] Common marker extensions to include
#
# This filter does not write any additional information to the context hash.
