I have created a tool that executes the code blocks included in
Markdown.
http://github.com/lempiji/md
I'm sure some of everyone have experienced that the code examples
in the documentation don't work.
With this tool, you can execute Markdown code directly and always
validate it with CI.
Recently, I created a tool to create a module dependency graph
for the D language.
The tool can compare two versions and visualize the differences.
I think it's useful for source reviews.
Try it if you are interested.
Some screenshots are included in the README.
