   <A NAME="expressions"><h3>Expressions</h3>
  -Expressions are used to define color and display rules in Chainsaw.  An expression is a
textual representation of a rule, and provides the ability to perform queries against a collection
of logging events.  As each logging event is examined by the rule, if the event passes the
rule's evaluation, the operation associated with the rule is performed (for example, the event
may be assigned a color or added to the display).  Log4J's rule expression syntax provides
access to all of the logging event's fields, a number of operators, and the ability to control
precedence.
