Detailed Description

Declarations having to do with the four output streams.

ARTS uses four output streams: out0 to out3, where out0 has the highest priority, out3 the lowest. These are global variables. They are intended to be used as follows:

• out0: Error messages
• out1: Output of the `engine'
• out2: Important workspace method output
• out3: Unimportant workspace method output

The classes associated with the four output stream variables have the same name, but start with a capital letter: Out0, Out1, Out2, and Out3.
