All Implemented Interfaces:

```
public class Output
extends Object
implements Serializable
```
Outputs and logs system messages, errors, and other various items printed as a result of a run.
Output maintains zero or more logs, which contain Writers which write out stuff. Each log has an associated verbosity; if request is made to write text to a log, and the text's maximal verbosity is lower than the verbosity of the log, the log will not write it. Each Output instance also has an instance-level global verbosity; incoming requests to write text are additionally subject to this verbosity test. Lastly, the Output class itself has a global verbosity as well. This last verbosity is useful for shutting down writing to all logs in the entire system in a simple way.
When the system fails for some reason and must be started back up from a checkpoint, Output's log files may be overwritten. Output offers three approaches here. First, Output can clear the log file and overwrite it. Second, Output can append to the existing log file; because checkpoints are only done occasionally, this may result in duplicate outputs to a file, so keep this in mind. Third, Output can keep certain written text, typically announcements, in memory; this text gets written out into the checkpoint file, and so it is sound.
There are several kinds of announcements, in different levels of importance.
1. FATAL ERRORs. These errors cause the system to exit(1) immediately.
2. Simple ERRORs. These errors set the "errors" flag to true; at the end of a stream of simple errors, the system in general is expected to exit with a fatal error due to the flag being set. That's the protocol anyway. On restart from a checkpoint, if there were any simple errors, the system ends with a fatal error automatically.
3. WARNINGs. These errors do not cause the system to exit under any circumstances.
4. MESSAGEs. Useful facts printed out for the benefit of the user.
5. SYSTEM MESSAGEs. Useful system-level facts printed out for the benefit of the user.
Output will also store all announcements in memory by default so as to reproduce them if it's restarted from a checkpoint. You can change this behavior also by

    Deprecated. Verbosity no longer has an effect.
    
    Creates a new log of minimal verbosity verbosity and adds it to Output. This log will write to the file file, and may or may not post announcements to the log. If the log must be reset upon restarting from a checkpoint, it will append to the file or erase the file and start over depending on appendOnRestart. If appendOnRestart is false and postAnnouncements is true, then this log will repost all the announcements on restarting from a checkpoint. Returns the position of the log in Output's collection of logs -- you should use this to access the log always; never store the log itself, which may go away upon a system restart. The log can be compressed with gzip, but you cannot appendOnRestart and compress at the same time.
