*
* The tiff images of bitmaps fonts, which are used as input
* to this generator, are supplied in Leptonica in the prog/fonts
* directory. The tiff images were generated from the PostScript files
* in that directory, using the shell script prog/ps2tiff. If you
* want to generate other fonts, modify the PostScript files
* and use ps2tiff. ps2tiff uses GhostScript.
