Groff takes standard text and formatting commands as input and produces formatted output.
The created documents can be shown on a display or printed on a printer.
Groff's formatting commands allow you to specify font type and size, bold type, italic type, the number and size of columns on a page, and more.
You should install groff if you want to use it as a document formatting system.
Groff can also be used to format man pages. If you are going to use groff with the X Window System, you'll also need to install the groff-gxditview package.
