I've been trying to understand how to properly use STREAM and no matter what I do, I always get one of those two errors:

I've tried to simplify my stream script to: #!/usr/local/bin/python import sys for line in sys.stdin: print line Without any luck (I get the POStream error). What am I missing? -- Pierre-Luc Brunet
