+.Sh NAME
+.Nm fpr
+.Nd print Fortran file
+.Sh SYNOPSIS
+.Nm fpr
+.Sh DESCRIPTION
+.Nm Fpr
+is a filter that transforms files formatted according to
+Fortran's carriage control conventions into files formatted
+according to
+.Ux
+line printer conventions.
+.Pp
+.Nm Fpr
+copies its input onto its output, replacing the carriage
+control characters with characters that will produce the intended
+effects when printed using
+.Xr lpr  1  .
+The first character of each line determines the vertical spacing as follows:
+.Bd -ragged -offset indent -compact
+.Bl -column Character
+.It Blank	One line
+.It 0	Two lines
+.It 1	To first line of next page
+.It +	No advance
+.El
+.Ed
+.Pp
+A blank line is treated as if its first
+character is a blank. A blank that appears as a carriage control
+character is deleted. A zero is changed to a newline.  A one is
+changed to a form feed. The effects of a "+" are simulated using
+backspaces.
