Installation:
> pip install git+https://github.com/phfaist/flm-htmlplus
This FLM extension package provides the flm_htmlplus workflow
(--workflow=flm_htmlplus) which adds some processing levels
to FLM's default HTML output. Mathematical equations can be
compiled into SVG elements. You can also generate PDF output
(internally, this uses an instance of Chrome to print the
generated HTML content to a PDF document).
