angle-grinder, slice and dice log files on the command line.

Angle-grinder allows you to parse, aggregate, sum, average, min/max, percentile,
and sort your data. You can see it, live-updating, in your terminal.
Angle grinder is designed for when, for whatever reason, you don't have your
data in graphite/honeycomb/kibana/sumologic/splunk/etc. but still want to be
able to do sophisticated analytics.

Angle grinder can process well above 1M rows per second (simple pipelines as
high as 5M), so it's usable for fairly meaty aggregation. The results will live
update in your terminal as data is processed. Angle grinder is a bare bones
functional programming language coupled with a pretty terminal UI.
