+ (description "WeasyPrint helps web developers to create PDF documents. It
+turns simple HTML pages into gorgeous statistical reports, invoices, tickets,
+etc.
+
+From a technical point of view, WeasyPrint is a visual rendering engine for
+HTML and CSS that can export to PDF and PNG. It aims to support web standards
+for printing.
+
+It is based on various libraries but not on a full rendering engine like
+WebKit or Gecko. The CSS layout engine is written in Python, designed for
+pagination, and meant to be easy to hack on. Weasyprint can also be used as a
+python library.
