Detailed Description

This file contains logging classes.

The macros LBERROR, LBWARN, LBINFO and LBVERB output messages at their respective logging level, if the level is active. They use a per-thread lunchbox::Log instance, which is a std::ostream. LBVERB is always inactive in release builds.

Definition in file log.h.
