	# The DejaVu fonts are now bundled with the library and don't need
	# to be found in TTF_DIR. Since most of the fonts supported by
	# JpGraph are corefonts, we point the sole TTF_DIR towards them for
	# maximum impact. Why not apply the patch unconditionally? We want
	# to avoid a situation where TTF fonts appear to work, but then
	# break without warning when the user e.g. removes corefonts. By
	# applying the patch conditionally, we ensure a dependency on
	# media-fonts/corefonts before anything will work.

	# Some of the documentation and examples are shipped in the "src"
