+wxProcess also supports IO redirection of the child process. For this, you have
+to call its \helpref{Redirect}{wxprocessredirect} method before passing it to 
+\helpref{wxExecute}{wxexecute}. If the child process was launched successfully, 
+\helpref{GetInputStream}{wxprocessgetinputstream}, 
+\helpref{GetOutputStream}{wxprocessgetoutputstream} and 
+\helpref{GetErrorStream}{wxprocessgeterrorstream} can then be used to retrieve
+the streams corresponding to the child process stdandard output, input and
+error output respectively.
