8.2 Font Files

The gtroff font format is roughly a superset of the ditroff font format (as used in later versions of AT&T troff and its descendants). Unlike the ditroff font format, there is no associated binary format; all files are text files.1 The font files for device name are stored in a directory devname. There are two types of file: a device description file called DESC and for each font f a font file called f.


[1] Plan 9 troff has also abandoned the binary format.
