- The initial plan is to create a structure for general information needed
- to log to a file.
-
- Initally I'll hard code the neccesary stuff to start a log, this should
- probably be moved elsewhere when some code is written to read the log
- file locations from the config files.
-
- As a more longterm idea, I'll code this so that the data struct can be
- duplicated to allow multiple concurrent log files, although this is
- probably a recipe for wasted resources.
