Milliseconds

A Nginx access log parser.

First version takes an access log file as parameter, and outputs summary in JSON format. The JSON output is backwards compatible with the old Node.js based Millseconds-js.

NOTE! This project is in very early stages and has known bugs and limitations, little error handling and no optimizations.
