+.Sh DESCRIPTION
+.Nm More
+is a filter for paging through text one screenful at a time. This version
+is especially primitve. Users should realize that
+.Xr less 1
+provides
+.Xr more 1
+emulation and extensive enhancements.

+Command line options are described below.

+.It Fl d
+.Nm more
+will prompt the user with the message "[Press space to continue, 'q' to
+quit.]" and will display "[Press 'h' for instructions.]" instead of ringing
+the bell when an illegal key is pressed.
+.It Fl l
+.Nm more
+usually treats
+.Ic \&^L
+(form feed) as a special character, and will pause after any line that
+contains a form feed. The

+option will prevent this behavior.
+.It Fl f
+Causes
+.Nm more
+to count logical, rather than screen lines (i.e., long lines are not
+folded).
+.It Fl p
+Do not scroll. Instead, clear the whole screen and then display the text.

+remainder of each line as it is displayed.
+.It Fl s
+Squeeze multiple blank lines into one.
+.It Fl u
+Suppress underlining.
+.It Ic +/
+The
+.Ic +/
+option specifies a string that will be searched for before
