-<h2>wxProcess</h2>
-
-wxProcess lets you get notified when an asyncronous child process
-started by wxExecute terminates, and also to get input/output streams
-for the child process's stdout, stderr and stdin.
-
-<p>
-This demo launches a simple python script that echos back on stdout
-lines that it reads from stdin. You can send text to the echo
-process' stdin by typing in the lower textctrl and clicking Send.
-
-<p>
-Clicking the Close Stream button will close the demo's end of the
-stdin pipe to the child process. In our case that will cause the
-child process to exit its main loop.
