Jev GitHub repos

Code you can read, fork and run: jev-ultrafast, OpenJev, nanojev, jevlike, simplejev, jev-trader, jev-mcp and the rest. Each repo calls Jev for a decision — which link to follow, which bucket a ticket goes in, which move to make — and the figures on a card are the ones its author published.
