 /*
 /*

-* Purpose:  Document/view architecture demo for wxWindows class library
-*           Run with no arguments for multiple top-level windows, -single
-*           for a single window.
-*/
+    This sample show document/view support in wxWidgets.
+
+    It can be run in several ways:
+        * With "--mdi" command line option to use multiple MDI child frames
+          for the multiple documents (this is the default).
+        * With "--sdi" command line option to use multiple top level windows
+          for the multiple documents
+        * With "--single" command line option to support opening a single
+          document only
+
+    Notice that doing it like this somewhat complicates the code, you could
+    make things much simpler in your own programs by using either
+    wxDocParentFrame or wxDocMDIParentFrame unconditionally (and never using
+    the single mode) instead of supporting all of them as this sample does.
