  14     This sample show document/view support in wxWidgets.
  15
  16     It can be run in several ways:
  17         * With "--mdi" command line option to use multiple MDI child frames
  18           for the multiple documents (this is the default).
  19         * With "--sdi" command line option to use multiple top level windows
  20           for the multiple documents
  21         * With "--single" command line option to support opening a single
  22           document only
  23
  24     Notice that doing it like this somewhat complicates the code, you could
  25     make things much simpler in your own programs by using either
  26     wxDocParentFrame or wxDocMDIParentFrame unconditionally (and never using
  27     the single mode) instead of supporting all of them as this sample does.
