|
|
|
9 # When the command is completed, it checks to see if the exit code was zero.
|
|
|
10 # if so - the command is assumed to have succeeded - the STDERR file is discarded.
|
|
|
11 # if not - the command is assumed to have failed, and the STDERR file is dumped to the real STDERR

|
14 # Use this wrapper for tools which insist on writing stuff to STDERR even if they succeeded -
|
|
|
15 # which throws galaxy off balance.
