Program: PCB.C
Author : Kim Moser
Date   : 02/17/89
System : IBM PC / Borland Turbo-C 2.0
Descrip: Copies text from stdin to stdout, removing newlines (except where
	 explicitly requested via "\n").

Usage  : PCB

This text will be
strung together because
its lines do not begin
with periods ('.').

.This text begins on
.a new line and will
.be formatted exactly
.as you see it, because
.each of its lines
.begins with a period.
