#The plotutils package contains extra X fonts.	These fonts are not installed
#in the current ebuild.	 The commented out ebuild lines below are for future
#reference when this ebuild may be updated to install the fonts.
#NOTE: The current method does not play nice with X and sandbox.  Most of the
#font installation procedures should probably be moved to pkg_postinst.
#See Bug# 30 at http://bugs.gentoo.org/show_bug.cgi?id=30
