/*
-* Purpose: Document/view architecture demo for wxWidgets 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.
