Description

This module is a logger with adjustable verbosity for commandline programs. Different verbosity levels can have different colors and styles applied and specific functions or methods can get extra verbosity. Message colors and styles are fully user-definable.

Additional functions are provided for displaying summaries of all warnings or errors encountered. Stack traces can been shown on demand or whenever there are warnings or errors.

This is a strictly functional module (no use of objects or methods). Tests have yet to be written.
Full documentation is available here and usage examples can be found in the examples/ directory.
