 wxStandardPaths returns the standard locations in the file system and should be
-used by the programs to find their data files in a portable way.
-
-Please note that this is not a real class because object of this type are never
-created but more a namespace containing the class methods which are all static,
-so to use wxStandardPaths simply call its methods directly.
+used by applications to find their data files in a portable way.
 
 In the description of the methods below, the example return values are given
 for the Unix, Windows and Mac OS X systems, however please note that these are
-just the examples and the actual values may differ. Most importantly:
-\begin{itemize}
-    \item Unix: \texttt{/usr} should in general be replaced by the
-        program installation prefix which is by default \texttt{/usr/local} but
-        may be any other path as well.
-    \item Windows: the system administrator may change the standard
-        directories locations, i.e. the Windows directory may be named
-        \texttt{W:$\backslash$Win2003} instead of default
-        \texttt{C:$\backslash$Windows}
-\end{itemize}
+just the examples and the actual values may differ. For example, under Windows:
+the system administrator may change the standard directories locations, i.e.
+the Windows directory may be named \texttt{W:$\backslash$Win2003} instead of
+the default \texttt{C:$\backslash$Windows}.
 
 The strings \texttt{\textit{appname}} and \texttt{\textit{username}} should be
-replaced with the value returned by \helpref{wxApp::GetAppName}{wxappgetappname} 
-and the name of the currently logged in user, respectively.
+replaced with the value returned by \helpref{wxApp::GetAppName}{wxappgetappname}
+and the name of the currently logged in user, respectively. The string
+\texttt{\textit{prefix}} is only used under Unix and is \texttt{/usr/local} by
+default but may be changed using \helpref{SetInstallPrefix}{wxstandardpathssetinstallprefix}.
 
 The directories returned by the methods of this class may or may not exist. If
 they don't exist, it's up to the caller to create them, wxStandardPaths doesn't
 do it.
 
-Finally note that under Mac, these functions only work for the bundled
-applications.
+Finally note that these functions only work with standardly packaged
+applications. I.e. under Unix you should follow the standard installation
+conventions and under Mac you should create your application bundle according
+to the Apple guidelines. Again, this class doesn't help you to do it.
+
+This class is MT-safe: its methods may be called concurrently from different
+threads without additional locking.
