This directory contains  TextbookPSCyr free sans-serif fonts (regular,bold,italic). To use them to print graphics with rusian text annotations, *.pfb files have to be made available to ghostscript (copy them to /usr/share/ghostscript/fonts directory and add their description to ghostscript's Fontmap.GS file
	/TextbookPSCyr-Italic 	(textb18.pfb);
	/TextbookPSCyr-Regular 	(textb19.pfb);
	/TextbookPSCyr-Bold	(textb20.pfb);
)  
For this fonts to be used in R postscript device, paths to *.afm files have to be specified as well as proper encoding vector (this one depends on locale, for ru_RU.KOI8-R locale use file koi8r.enc).
