# This script is runnable as is, all you need to do is supply your own API key
# in the ANVIL_API_KEY environment variable.
#
# ANVIL_API_KEY=<yourAPIKey> python examples/generate-html-to-pdf.py
#
# The filled PDF will be saved to `output/generate-html-output.pdf`. You can
# open the filled PDF immediately after saving the file on OSX machines with
# the `open` command:
#
# ANVIL_API_KEY=<yourAPIKey> python examples/generate-html-to-pdf.py \
#   && open output/generate-html-output.pdf

                    Lorem Ipsum is simply dummy text of the printing and typesetting
                    industry. Lorem Ipsum has been the industry's standard dummy text
                    ever since the <strong>1500s</strong>, when an unknown printer took
                    a galley of type and scrambled it to make a type specimen book.

                    Contrary to popular belief, Lorem Ipsum is not simply random text.
                    It has roots in a piece of classical Latin literature from
                    <i>45 BC</i>, making it over <strong>2000</strong> years old.
