The Kite standard library consists of several important libraries. All of these libraries should be part of an implementation of Kite.
The documentation for these can be generated by executing:
import "System.doc";
out = make System.doc.outputters.html_outputter();
doc = System.doc|generate_doc(__root);
doc|output(out);
You can also view the documentation online by going to http://www.kite-language.org/docs/kdoc-[version]/__root.html, where [version] is the version of your copy of the interpreter (starting from 1.0b4 on).
