 Synopsis:         Fonts from the SVG-Font format
 Description:      Native font support for the diagrams framework (<http://projects.haskell.org/diagrams/>). Note that this package can be used with any diagrams backend, not just the SVG backend.  The SVG-font format is easy to parse
                   and was therefore chosen for a font library completely written in Haskell.
