Liquid War 6 uses stdout to output important messages,
and stderr to log warnings and errors.
It will also use syslog if available.
Additionnally, a verbose log is available in $HOME/.liquidwar6/log.csv.
You can read this using any spreadsheet software capable of reading
csv file. It uses the tab (\t) character as a separator.
It contains valuable informations including version and most default
values for the game, and for each line logged, it says where in the
code the log function was called. A must-have for debugging.
