How to only show last n lines for the first time run?

[daqing]

I'm using this module to write a program that prints lines from multiple log file, and when at the first time, it prints ALL the contents of a log file, which takes a long time.

I'd like to know if this module can provide a config to limit how many lines can return on the first time?

just found out that, there exists an option to set Location.
