+# Name:        wxversion
+# Purpose:     Allows a wxPython program to search for alternate 
+#              installations of the wxPython packages and modify sys.path
+#              so they will be found when "import wx" is done.

+"""
+If you have more than one version of wxPython installed this module
+allows your application to choose which version of wxPython will be
+imported when it does 'import wx'.  The main function of this module
+is `select` and you use it like this::
+
+    import wxversion
+    wxversion.select('2.4')
+    import wx
+
+Or additional build options can also be selected, although they will
+not be required if they are not installed, like this::
+
+    import wxversion
+    wxversion.select('2.5.3-unicode')
+    import wx
+
+Or you can require an exact match on the build options like this::
+
+    import wxversion
+    wxversion.select('2.5.3-unicode', optionsRequired=True)
+    import wx
+
+Finally you can also specify a collection of versions that are allowed
+by your application, like this::
+
+    import wxversion
+    wxversion.select(['2.5.4', '2.5.5', '2.6'])
+    import wx
+
+
+Of course the default wxPython version can also be controlled by
+setting PYTHONPATH or by editing the wx.pth path configuration file,
+but using wxversion will allow an application to manage the version
+selection itself rather than depend on the user to setup the
+environment correctly.
+
+It works by searching the sys.path for directories matching wx-* and
+then comparing them to what was passed to the select function.  If a
+match is found then that path is inserted into sys.path.
+
+NOTE: If you are making a 'bundle' of your application with a tool
+like py2exe then you should *not* use the wxversion module since it
+looks at the filesystem for the directories on sys.path, it will fail
+in a bundled environment.  Instead you should simply ensure that the
+version of wxPython that you want is found by default on the sys.path
+when making the bundled version by setting PYTHONPATH.  Then that
+version will be included in your bundle and your app will work as
+expected.  Py2exe and the others usually have a way to tell at runtime
+if they are running from a bundle or running raw, so you can check
+that and only use wxversion if needed.  For example, for py2exe::
+
+    if not hasattr(sys, 'frozen'):
+        import wxversion
+        wxversion.select('2.5')
+    import wx
+
+More documentation on wxversion and multi-version installs can be
+found at: http://wiki.wxpython.org/index.cgi/MultiVersionInstalls

+    Search for a wxPython installation that matches version.  If one
+    is found then sys.path is modified so that version will be
+    imported with a 'import wx', otherwise a VersionError exception is
+    raised.  This function should only be called once at the beginning
+    of the application before wxPython is imported.
+
+        :param versions: Specifies the version to look for, it can
+            either be a string or a list of strings.  Each string is
+            compared to the installed wxPythons and the best match is
+            inserted into the sys.path, allowing an 'import wx' to
+            find that version.
+
+            The version string is composed of the dotted version
+            number (at least 2 of the 4 components) optionally
+            followed by hyphen ('-') separated options (wx port,
+            unicode/ansi, flavour, etc.)  A match is determined by how
+            much of the installed version matches what is given in the
+            version parameter.  If the version number components don't
+            match then the score is zero, otherwise the score is
+            increased for every specified optional component that is
+            specified and that matches.
+
+            Please note, however, that it is possible for a match to
+            be selected that doesn't exactly match the versions
+            requested.  The only component that is required to be
+            matched is the version number.  If you need to require a
+            match on the other components as well, then please use the
+            optional ``optionsRequired`` parameter described next.
+
+        :param optionsRequired: Allows you to specify that the other
+             components of the version string (such as the port name
+             or character type) are also required to be present for an
+             installed version to be considered a match.  Using this
+             parameter allows you to change the selection from a soft,
+             as close as possible match to a hard, exact match.
