Why these Tags: an agent read the README and quoted it
- Reverse engineering from the readme:
programs to define a new class at runtime and to modify a class file when the JVM loads it.
An agent gave these Tags from the fixed Tag list in the AwesomeRepos source code. A code check kept each Tag only when its quote is in the text. A wrong Tag? Report an errorwith the form at the end of this page.

The timeline comes from the creation date and the releases on the Repository Host, the Admission, the Star History, and the Observations. Star milestones show only when the Star History records the day. The list shows up to 5 stable releases from the latest 10 releases recorded. When none of them is stable, one item counts the pre-releases. On the chart of net stars each day, a solid line marks each recorded release.

Health facts
Measured facts in four separate dimensions, each with a date and a source. AwesomeRepos does not add them into one score.
