How To Install groff on CentOS 8

groff is A document formatting system

Introduction

In this tutorial we learn how to install groff on CentOS 8.

What is `groff`

Groff is a document formatting system. 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. Groff can also be used to format man pages. If you are going to use groff with the X Window System, you will also need to install the groff-x11 package.
