Binary package “mknfonts.tool” in ubuntu trusty

Create nfont packages for GNUstep

 This doesn't completely automate the process of creating nfont-packages,
 but it can do most of the bulk work for you.
 .
 This works with .ttf, .pfa, .pfb, .afm, most formats that freetype can handle
 and provide postscript names for.
