Linux "grotty" Command Line Options and Examples
groff driver for typewriter-like devices
grotty translates the output of GNU troff into a form suitable for typewriter-like devices. Normally grotty should be invoked by using the groff command with a -Tascii, -Tlatin1 or -Tutf8 option on ASCII based systems, and with -Tcp1047 and -Tutf8 on EBCDIC based hosts. If no files are given, grotty reads the standard input.
grotty [ -bBcdfhioruUv ] [ -Fdir ] [ files... ]
It is possible to have whitespace between the -F option and its parameter.
