Echo Task

Echo

Description

Echoes a message to the current loggers and listeners which means System.out unless overridden. A level can be specified, which controls at what logging level the message is filtered at.

The task can also echo to a file, in which case the option to append rather than overwrite the file is available, and the level option is ignored
