+Please refer to the installation instructions for wxGTK or wxX11. The only
+change for wxUniversal is that you must add "--enable-universal" switch to
+the configure command line and for wxX11 even this is unnecessary, i.e. it
+is enabled by default.

+4. Running wxUniv programs
+--------------------------
+
+wxUniv programs all honour the standard option "--theme" which allows to
+specify the theme to be used by name. Currently there are the following
+themes:
+
+a) win32 -- Windows 95 look and feel
+b) metal -- based on win32 but with gradient backgrounds
+c) gtk -- GTK+ 1.x standard look and feel
