how Brenthy manages logging
The logfiles in which Brenthy writes the output of its runtime activities consists of the newest log file called Brenthy.log and a folder called .log_archive which contains older logfiles.
When installed, the location of Brenthy.log and .log_archive is the root of the installation directory.
When not installed, their location is {USER_APPDATA_DIR}/Brenthy/
At the time of writing, Brenthy is configured to keep Brenthy.log at less than 1MiB in size and keeps up to 50 old log files (each around 1MiB in size) before deleting them. These settings will be customisable in the future, and are hackable anyway!
