-If the
-.B \-clear
-switch is used and
-.BR scan 's
-output is directed
-to a terminal, then
-.B scan
-will consult the environment variables
-.B $TERM
-and
-.B $TERMCAP
-to determine your terminal type in order
-to find out how to clear the screen prior to exiting. If the
-.B \-clear
-switch is used and
-.BR scan 's
-output is not directed to a terminal
-(e.g., a pipe or a file), then
-.B scan
-will send a formfeed prior
-to exiting.

-For example, the command:
+The command:
.PP
.RS 5

the

.SH BUGS
-The argument to the
-.B \-format
-switch must be interpreted as a single
-token by the shell that invokes
-.BR scan .
-Therefore, one must usually
-place the argument to this switch inside double\-quotes.
-.PP
The value of each
.I component
escape is set by
