MKTRFN ====== The mktrfn program creates troff font description files for neatroff from AFM (Adobe Font Metrics), TrueType, and OpenType fonts. For TrueType and OpenType fonts, mktrfn depends on the otfdump program that comes with heirloom-docutils. See the output of "mktrfn -h" for the available options. The included ./gen.sh script invokes mktrfn to create a complete output device for neatroff. Change the variables in that file before running it.
