"...calls to the Mediawiki API, only grabs the recent changes from the last call, denormalizes the output, and outputs it in a log like format."It's useful for things like Splunk, log tools, or data visualization/analytic tools that prefer to consume things in a denormalized deterministic log format.
It's poorly written I should confess, but done is better than perfect (feel free to improve a fork and pull request). I've always wanted to release something as open source. In the past I've contributed to open source via docs, submitted bugs, beta tested, etc, but I've never contributed code back to the community. It's time I finally did this.
