Detailed Description

Debugging information.

The LLog class provides an output stream for debugging information.
The level of verbosity can be assigned setting the LOUVRE_DEBUG environment variable to a non negative integer value.
All messages are directed to the stdout stream, except for those generated by error() and fatal(), which are written to the stderr stream.

Verbosity levels

LOUVRE_DEBUG=0

Disables messages except those generated by log().

LOUVRE_DEBUG=1

Prints messages generated by log() and fatal().

LOUVRE_DEBUG=2

Prints messages generated by log(), fatal() and error().

LOUVRE_DEBUG=3

Prints messages generated by log(), fatal(), error() and warning().

LOUVRE_DEBUG=4

Prints messages generated by log(), fatal(), error(), warning() and debug().
