 .SH DESCRIPTION
-.sp
-.LP
 The \fBbc\fR utility implements an arbitrary precision calculator. It takes
 input from any files given, then reads from the standard input. If the standard
 input and standard output to \fBbc\fR are attached to a terminal, the
 invocation of \fBbc\fR is  \fIinteractive\fR, causing behavioral constraints
 described in the following sections. \fBbc\fR processes a language that
 resembles C and is a preprocessor for the desk calculator program \fBdc\fR,
 which it invokes automatically unless the \fB-c\fR option is specified. In this
 case the \fBdc\fR input is sent to the standard output instead.
 .SH USAGE
