MKTRFN ====== The mktrfn program creates troff font description files for neatroff from AFM (Adobe Font Metrics) and TTF (TrueType Font) files. OpenType fonts can be first converted to TTF (see ./gen.sh, for instance). 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. By default, font features are ordered as specified in the font. However, in some languages like Arabic, some features should be applied first. The -O argument of mkfn allows specifying the features to output before any other feature. For instance for Arabic, one should pass "-O ccmp,rlig,calt,liga,dlig,cswh,mset" to mkfn.
