+"""
+This is a simple little echo program that is used by the wxProcess
+demo.  It reads lines from stdin and echos them back to stdout, until
+there is an EOF on stdin.
+
+Enter text in the field below to send to the stdin of the echo
+process.  Clicking on 'Close Stream' will close the stream in the
+demo, and then echo.py should terminate too...
