Flog is a library for logging, with a dynamic tree-like structure.
It tries to make logging as painless as possible in the workflow of a developer.
Avoids costly refactoring of logging code at all costs.
Imagine you are writing software that uses printf to output messages to stdout.
Now imagine that the software grows exponentially into a zillion modules, and all of them need to output various messages to different outputs.
Flog is a way to control that behaviour in a clean fashion.

Features:

• Timestamping (with second or usec accuracy)
• Source code information (source file, line and function)
• Sublogs with names
• Message filtering
• Pluggable output modules (currently stdio and file)
• Suitable for deeply embedded systems as well as huge projects
• Certain features can be configured out of the build (currently 12 features)
