  21    <p>The principal purposes of using a debugger are so that you can stop your
  22 program before it terminates; or so that, if your program runs into
  23 trouble, you can investigate and find out why.
  24
  25    <p>Inside GDB, your program may stop for any of several reasons,
  26 such as a signal, a breakpoint, or reaching a new line after a
  27 GDB command such as <code>step</code>.  You may then examine and
  28 change variables, set new breakpoints or remove old ones, and then
  29 continue execution.  Usually, the messages shown by GDB provide
  30 ample explanation of the status of your program--but you can also
  31 explicitly request this information at any time.
  32
  33      <dl>
  34 <dt><code>info program</code>
  35      <dd>Display information about the status of your program: whether it is
  36 running or not, what process it is, and why it stopped.
