A somewhat fancy observer pattern library with features like named events and scoped subscriptions.

Evaluates Ruby code in your markdown, for awesome examples.

Updates project revision identifiers in software source files and associated change log. Can also build and package project archives as a zip and optionally commit, tag and push to a Git repo.

In ruby we use `# =>` as a comment marker that mean the immediately adjacent expression's expected value. There are gems like xmpfilter / seening_is_believing, which are to generate such comments. They are very useful. But so far we lack feature that does vice-versa; to check if the comment is actually the output of the expression. This is the library that does it.
