* How it works:
* Modules create their own logstream types (core will create one for 'file logging' for example) and create instances of these logstream types
- * and register interest in a certain logtype. Globbing is not here, with the exception of * - for all events.. loglevel is used to drop
+ * and register interest in a certain logtype. Globbing is not here, with the exception of * - for all events.. loglevel is used to drop
* events that are of no interest to a logstream.
*
* When Log is called, the vector of logstreams for that type is iterated (along with the special vector for "*"), and all registered logstreams
* NOTE: Somehow we have to let LogManager manage the non-blocking file streams and provide an interface to share them with various LogStreams,
* as, for example, a user may want to let 'KILL' and 'XLINE' snotices go to /home/ircd/inspircd/logs/operactions.log, or whatever. How
* can we accomplish this easily? I guess with a map of pre-loved logpaths, and a pointer of FILE *..
