The output levels for VIVO are determined by a file called
called [vitro-core]/webapp/config/log4j.properties

This file sets the general output level to INFO, which means that messages at the
INFO level or higher will be written to the log. Messages at DEBUG or lower
will not be written to the log.

The file also sets higher output levels for some classes that are otherwise too chatty with their
log their log messages. So for example, the StartupStatus class is assigned an output level of WARN.
This  This means that messages at the WARN level or higher will be written to the log,
and messages at INFO or lower will not.

Developers can make temporary changes to these settings by creating a file called
called [vitro-core]/webapp/config/debug.log4j.properties

When VIVO is rebuilt, the settings in this file will be used instead of the
settings the settings in the default file. A developer will commonly change the output level of the
classes the classes or packages he is currently working on, using this file.

The debug settings file is ignored by Git. As a result it remains unique to the individual
developer, and can be changed without concern.
