+Implementation Notes
+====================
+
+wxMicroWindows is essentially the wxMSW port + wxUniversal
+widgets. Lots of things in include/wx/univ/setup.h are switched
+off to allow the port to compile. There are also #ifdefs
+switching off further functionality, such as most wxBitmap
+functions, pending proper implementation.
+
+There are some WIN32 API functions not implemented by MicroWindows
+that are instead stubbed out in include/wx/msw/microwin.c,
+and 'implemented' in src/msw/microwin.c. Some of these functions
+are important, some less so. They will need to be implemented
+in due course. But implementing missing functionality in this way
+is preferably to proliferating many #ifdefs in the
+wxMSW/wxMicroWindows port itself.
