+whereever you checked out the wxWidgets module from CVS, or untarred
+the wxPython-src tarball to.  You can either substitute the $WXDIR text

+If you run into what appears to be compatibility issues between
+wxWidgets and wxPython while building wxPython, be sure you are using
+the wxWidgets sources included with the wxPython-src tarball or the
+CVS snapshot, and not a previously installed version or a version
+installed from one of the standard wxWidgets installers.  With the
+"unstable" releases (have a odd-numbered minor release value, where

+differences between the W.X.Y release of wxWidgets and the W.X.Y.Z

+   If *not* using my scripts then you can do it by hand by directly
+   executing nmake with a bunch of extra command line parameters.
+   The base set are::
+
+       -f makefile.vc OFFICIAL_BUILD=1 SHARED=1 MONOLITHIC=1 USE_OPENGL=1
+
+   If doing a debug build then add::
+
+       BUILD=debug 
+
+   otherwise add these::
+
+       DEBUG_FLAG=1 CXXFLAGS=/D__NO_VC_CRTDBG__ WXDEBUGFLAG=h BUILD=release
+
+   If doing a Unicode build then add these flags::
+
+       UNICODE=1 MSLU=1
+
+   Now, from the %WXDIR%\\build\\msw directory run nmake with your
+   selection of command-line flags as described above.  Repeat this
+   same command from the following directories in order to build the
+   contrib libraries::
+
+       %WXDIR%\contrib\build\gizmos
+       %WXDIR%\contrib\build\stc
+       %WXDIR%\contrib\build\ogl
+
+    Note, that the ogl lib build will need an additional flag::
+
+       CPPFLAGS="-DwxUSE_DEPRECATED=0"
