+# Fake Apache Log Generator
+
+This script generates a boatload of fake apache logs very quickly. Its useful for generating fake workloads for [data ingest](http://github.com/streamsets/datacollector) and/or analytics applications.
+
+It can write log lines to console, to log files or directly to gzip files.
+
+It utilizes the excellent [Faker](https://github.com/joke2k/faker/) library to generate realistic ip's, URI's etc.
