# [DESCRIPTION](#DESCRIPTION)

This module acts exactly like Log::Dispatch::File except that it obtains an exclusive lock on the file while opening it.

Note that if you are using this output because you want to write to a file from multiple processes, you should open the file with the append "mode" (">>"), or else it's quite likely that one process will overwrite another.
