+%description
+Less is a pager. A pager is a program that displays text files.
+Other pagers commonly in use are more and pg. Pagers are often
+used in command-line environments like the Unix shell and the MS-DOS
+command prompt to display files.
+
+Less is not an editor. You can't change the contents of the file
+you're viewing. Less is not a windowing system. It doesn't have
+fancy scroll bars or other GUI (graphical user interface) elements.
