Log types extensions are to be used like any other LogDistiller extension.
New log types are done as Java classes extending net.sf.logdistiller.LogEvent, with a corresponding LogEvent.Factory.
To declare the new log type to LogDistiller, create a new LogTypes subclass to implement public List defineLogTypes() API and write a logdistiller.properties resource file like following:
logtypes=[LogTypes subclass' name]
Just take a look at one extension to see how simple it is.
