A filename of - also causes grotty to\nread the standard input. Output is written to the standard output.\n\nBy default, grotty emits SGR escape sequences (from ISO 6429, also called ANSI color escapes)\nto change text attributes (bold, italic, colors). This makes it possible to have eight dif‐\nferent background and foreground colors; additionally, bold and italic attributes can be used\naatt tthhee ssaammee ttiimmee (by using the BI font).\n\nThe following colors are defined in tty.tmac: black, white, red, green, blue, yellow, ma‐\ngenta, cyan. Unknown colors are mapped to the default color (which is dependent on the set‐\ntings of the terminal; in most cases, this is black for the foreground and white for the\nbackground).\n\nUse the -c switch to revert to the old behaviour, printing a bold character c with the se‐\nquence “c BACKSPACE c” and an italic character c by the sequence “ BACKSPACE c”. At the\nsame time, color output is disabled. The same effect can be achieved by setting either the\nGROFFNOSGR environment variable or using the ‘sgr’ X command (see below).\n\n(Debian-specific: The old behaviour is the default when using the man and mdoc macro pack‐\nages, because most pagers either fail to cope with SGR escape sequences or need special op‐\ntions to do so. SGR output can be re-enabled permanently by editing /etc/groff/man.local and\n/etc/groff/mdoc.local, or temporarily by setting the GROFFSGR environment variable to some‐\nthing non-empty.)\n\nFor SGR support, it is necessary to use the -R option of less(1) to disable the interpreta‐\ntion of grotty's old output format. Consequently, all programs which use less as the pager\nprogram have to pass this option to it. For man(1) in particular, either add -R to the PAGER\nenvironment variable, e.g.\n\nPAGER=\"/usr/bin/less -R\"\nexport PAGER\n\nor use the -P option of man to set the pager executable and its options, or modify the con‐\nfiguration file of man in a similar fashion. Note that with some man(1) versions, you have\nto use the MANPAGER environment variable instead.\n\ngrotty's old output format can be displayed on a terminal by piping through ul(1). Pagers\nsuch as more(1) or less(1) are also able to display these sequences. Use either -B or -U\nwhen piping into less(1); use -b when piping into more(1). There is no need to filter the\noutput through col(1) since grotty never outputs reverse line feeds.\n\nThe font description file may contain a command\n\ninternalname n\n\nwhere n is a decimal integer. If the 01 bit in n is set, then the font is treated as an\nitalic font; if the 02 bit is set, then it is treated as a bold font. The code field in the\nfont description field gives the code which is used to output the character. This code can\nalso be used in the \\N escape sequence in troff.\n\nIf the DESC file contains the keyword unicode, grotty emits Unicode characters in UTF-8 en‐\ncoding. Otherwise, it emits characters in a single-byte encoding depending on the data in\nthe font description files. See the grofffont(5) man page for more details.\n\n### OPTIONS\n\nWhitespace is permitted between a command-line option and its argument.\n\n#### -b -c\n\n#### -B -c\n\n#### -c\n\nbian-specific: This option is enabled by default when using the man and mdoc macro\npackages. It can be disabled by default permanently by editing /etc/groff/man.local\nand /etc/groff/mdoc.local, or temporarily by setting the GROFFSGR environment vari‐\nable to something non-empty.)\n\n#### -d\n\nleast one zero argument (and so are either horizontal or vertical) using -, |, and +\ncharacters. In a similar way, grotty handles \\D'p...' commands which consist entirely\nof horizontal and vertical lines.\n\n#### -f\n\nno output on its last line.\n\n#### -F\n\nfiles; name is the name of the device, usually ascii, latin1, utf8, or cp1047.\n\n#### -h\n\n#### -i\n\nbute for italic fonts (‘I’ and ‘BI’). Note that most terminals (including xterm)\ndon't support this. Ignored if -c is active.\n\n#### -o\n\noutput format has been activated with -c).\n\n#### -r\n\nbute for italic fonts (‘I’ and ‘BI’). Ignored if -c is active.\n\n#### -u -c\n\n#### -U -c\n\n#### -v\n\n### USAGE\n\ngrotty understands a single X command produced using the \\X escape sequence.\n\n\\X'tty: sgr n'\nIf n is non-zero or missing, enable SGR output (this is the default), otherwise use\nthe old drawing scheme for bold and underline.\n\n### ENVIRONMENT\n\nGROFFNOSGR\nIf set, the old drawing scheme for bold and underline (using the backspace character)\nis active. Colors are disabled.\n\nGROFFFONTPATH\nA list of directories in which to search for the devname directory in addition to the\ndefault ones.
