  .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.
