-Other Stuff
------------
+Starting with 2.5.3.0 the wx and wxPython package directories will be
+installed in a subdirectory of the site-packages directory, instead of
+directly in site-packages.  This is done to help facilitate having
+multiple versions of wxPython installed side-by-side.  Why would you
+want to do this?  One possible scenario is you have an app that
+requires wxPython 2.4 but you want to use the newest 2.5 to do your
+own development with.  Or perhaps you want to be able to test your app
+with several different versions of wxPython to ensure compatibility.
+Before everyone panics, rest asured that if you only install one
+version of wxPython then you should notice no difference in how things
+work.
+
+In addition to installing wxPython into a "versioned" subdirectory of
+site-packages, a file named `wx.pth` is optionally installed that will
+contain the name of the versioned subdirectory.  This will cause that
+subdirectory to be automatically added to the sys.path and so doing an
+"import wx" will find the package in the subdirectory like it would
+have if it was still located directly in site-packages.  I say
+"optionally" above because that is how you can control which install
+of wxPython is the default one.  Which ever version installs the
+wx.pth file will be the one that is imported with a plain "import wx"
+statement.  Of course you can always manipulate that by editing the
+wx.pth file, or by setting PYTHONPATH in the environment, or by the
+method described in the next paragraph.
+
+Finally, a new module named wxversion.py is installed to the
+site-packages directory.  It can be used to manipulate the sys.path at
+runtime so your applications can select which version of wxPython they
+would like to to have imported.  You use it like this::
+
+      import wxversion
+      wxversion.select("2.4")
+      import wx
+
+Then even though a 2.5 version of wxPython may be the default the
+application that does the above the first time that wx is imported
+will actually get a 2.4 version.  **NOTE:** There isn't actually a 2.4
+version of wxPython that supports this, but there will be.
+
