New issue 596: yt command does not produce helpful output https://bitbucket.org/yt_analysis/yt/issue/596/yt-command-does-not-produce-h... Matthew Turk: Currently, simply running "yt" indicates that something has gone wrong. This is actually not the case, and we should default to having a help output. This may be tricky to implement with argparse but can likely be done. Responsible: MatthewTurk
