Subject: subcommand: Don't print error messages to stdout.
X-Git-Url: http://git.tuebingen.mpg.de/libdai.git/tree?a=commitdiff_plain;h=4b006b9a403f59daee07d62fdc2553409872f14c;p=gsu.git

subcommand: Don't print error messages to stdout.

If an invalid command name was given, we print the list of available
commands, followed by an error message. The list of commands is
sent to stdout while the error message goes to stderr. This is a bit
unfortunate, so print both to stderr instead.
