+    Class to copy stderr to stdout.
+
+    This is intended for use in cronjobs,
+    where it is useful to have both stderr and stdout in the log file
+    but still have stderr so that the mailer gets any errors
+    The main script should be run unbuffered (-u)
+
+    Unfortunately Python does not seem to offer the equivalent of:
+    perl -[mM][-]module  execute "use/no module..." before executing program
+    ruby -rlibrary       require the library before executing your script
+    lua  -l name         require library 'name'
+    Thus the module has to be explicitly imported by the user script,
+    and the user must defing the 'ERRTEE' environment variable to enable it
+
