Don't instantiate tasks In practice they are just typed functions with attributes, having a reference to an object is just confusing. So: Task.run() is now a classmethod 2014-01-05 15:57:11 +01:00			`@classmethod`

Execute entries with a single string as shell commands Documentation says about that, but it's not implemented like that. If the command to be executed is an array with just one string, it's likely the user passed the entire command inside the string. Plus, they benefit from shell expansion of wildcards like '*'. 2015-03-27 11:23:58 -03:00			`shell = len(command) == 1`
