    Uses a project or repository's history to plot user contributions, displaying an elegant, colored graph of the file arborescence.

    After running it on quite different projects...

    • Python/Bash CI/Jenkins scripts
    • Qt apps: GoldenDict, Psi+
    • PHP website: Shaarli

    ...watching some vids on teh intartubez:

    • Minecraft: https://www.youtube.com/watch?v=zRjTyRly5WA
    • Linux kernel: https://www.youtube.com/watch?v=AhDiYPLo3p4
    • Python: https://www.youtube.com/watch?v=cNBtDstOTmA

    It allows to arbitrary spot some interesting implementation aspects (sorted by descending impact):

    • language-dependent trees (oh hai Java packages ^^)
    • framework-dependent trees
    • project-management method (none, Agile, TDD)

    Having a graphical tool also quickly shows:

    • the overall structure of the project (a bit cooler than a simple $ tree, way quicker than loading the project on an IDE)
    • the repartition of files (by extensions)
    • who are the most active contributors
    • what are the most modified files over time
    • who does what: additions, deletions, refactoring

    Some more CI-related matters:

    • are there any tests?
    • what is the source code / test code ratio? (we could expect a project/lib with N modules to have at least N test modules)
    • who initiates / implements / optimizes test code?
