=== Logging ===

You can configure logging by using the Java -Dlog.config=filename option.
This option uses a logging configuration file that allows you to enable and
disable specific logging messages. This is useful if you want to see
certain types of message that are not logged by default or choose where the
messages should be written. The configuration file contains details of the
handler(s) used to write the messages, parameters used to format the
messages and the severity of messages that should be logged at Java package
or class level, plus a default value. An example file is:

<pre>
# The default level FINE, WARNING, INFO, SEVERE 
.level=SEVERE
handlers: java.util.logging.FileHandler java.util.logging.ConsoleHandler 
# package or class name with .level appended and then the level
uk.me.parabola.imgfmt.level=INFO
uk.me.parabola.mkgmap.build.level=INFO
uk.me.parabola.mkgmap.main.Main.level=INFO
uk.me.parabola.mkgmap.main.MapMaker.level=INFO
uk.me.parabola.mkgmap.general.RoadNetwork.level=INFO
uk.me.parabola.mkgmap.general.MapLine.level=INFO
uk.me.parabola.mkgmap.osmstyle.level=INFO
uk.me.parabola.mkgmap.reader.osm.level=INFO
uk.me.parabola.mkgmap.reader.osm.xml.level=INFO
uk.me.parabola.mkgmap.reader.osm.RestrictionRelation.level=FINE
uk.me.parabola.mkgmap.reader.osm.Restriction.level=FINE
# For ConsoleHandler
java.util.logging.ConsoleHandler.level=WARNING
java.util.logging.ConsoleHandler.formatter=uk.me.parabola.log.UsefulFormatter
# For FileHandler
java.util.logging.FileHandler.level=FINE
java.util.logging.FileHandler.encoding=UTF-8
java.util.logging.FileHandler.formatter=uk.me.parabola.log.UsefulFormatter
java.util.logging.FileHandler.limit=20000000
java.util.logging.FileHandler.count=4
java.util.logging.FileHandler.pattern=mkgmap.log
java.util.logging.FileHandler.append=false
</pre>

The above example enables certain informational messages and uses FileHandler to send
them to a log file, with warning and error messages being also sent to stderr via
ConsoleHandler.

Mkgmap provides UsefulFormatter to help format messages, but you can use the
standard Java SimpleFormatter if you prefer.

In addition to the standard Java levels, mkgmap uses three additional levels
DIAGNOSTIC (1100), ECHO (1200) and OVERRIDE (1300) for messages from its
diagnostic options, echo/echotags style compiler actions and to display
mkgmap startup and completion information. You can use the numeric values but
not the names to specify these levels in a logging configuration file.

If you see messages that contain non-ASCII characters which are not displaying
properly in the console, you may need to use the Java -Dfile.encoding=<codepage>
option and/or precede the mkgmap command line with a chcp command to make
sure that the Java environment has the same code page as the shell it is
being run from. This is especially likely on the Windows platform where the
Java environment uses the Windows default code page, but the Windows command
shell normally uses a different code page.
