we have released a new version of Microlog. We now have a PatternFormatter that formats the logs the way you want it. It is inspired by the PatternLayout found in Log4j. We have also included a lot of new appenders.
From the projectpage: "MicroLog is a small logging library for Java ME (J2ME) like Log4j. It has support for logging to console, file, RecordStore, Canvas, Form, Bluetooth, a serial port (Bluetooth, IR, USB), Socket(incl SSL), UDP, Syslog, MMS, SMS, e-mail or to Amazon S3."
