Optional
directoryOptional journal directory. If not specified then automatically determined by looking in popular spots.
Optional
positionOptional position within the journal where to start at. Can be either a specific journal position or the string "end" to indicate starting at the end of the journal. Starting at the end only makes sense for watch mode to only watch for new events. In normal read mode you would simply read no events at all.
Optional
watchSet to true to watch the journal for new events. False (default) just reads the existing journal events and does not wait for new ones.
Options for reading journal files.
