I have published the following two Ruby gems:

• dom: You can describe HTML/XML DOM structures in Ruby language seamlessly with other parts of Ruby code. Node embedding is described as method chaining, which avoids unnecessary nesting, and confirms to the Rubyistic coding style.

• manager: Manager generates a user's manual and a developer's chart simultaneously from a single spec file that contains both kinds of information. More precisely, it is a document generator, source code annotation extracter, source code analyzer, class diagram generator, unit test framework, benchmark measurer for alternative implementations of a feature, all in one.

Comments and contributions are welcome.

I am preparing a web service that is coming out soon.
