                      2: Since spaces are thrown away, what do you do when
                      3: you want spaces? The answer is that you have to ask for
                      4: them explicitly.
                      5: If you type a "~" (tilde) it will be replaced by a space
                      6: on output; use one tilde for each space.
                      7: Thus to get
                      8: a + b
                      9: you need

                     14: Modify the equation in file "Example" so there is one space
                     15: around each of the operators =, + and -, so it looks like
                     16: 
                     17: a = b + c - d

                     19: Print it with neqn and nroff -ms to verify it.
