+fonts (TrueType, OpenType, Type 1, web fonts, etc.) in R graphs, and supports
+most output formats of R graphics including PNG, PDF and SVG.  Text glyphs
+will be converted into polygons or raster images, hence after the plot has
+been created, it no longer relies on the font files.  No external software
+such as Ghostscript is needed to use this package.")
