PTLog Top

This page is the top of PTLog support site.

PTLog focuses on (1) Pluggability of underlying logging frameworks, (2) Type-based categorization and (3) some formatting utility on Logging.

PTLog does not compete against any other "pure" logging framework (e.g.: JDK Logging API and Apache Log4j), but can co-operate with them as abstraction layer on them.

Please see "What PTLog is" for detail.
