When the project that would eventually become Liza was initially developed,
Node.js was still very young and there were no well established testing
frameworks. That has since changed.
Texinfo is the documenation format of the GNU operating system and can
produce output in a variety of useful formats, including info, HTML, and
PDF.
The HTML output is of particular importance here, since Liza is a JavaScript
framework.
``Building'' Liza will not be required to use it; see ease.js for the style
of building that will be used here. In particular: the build process will be
used for minification and the creation of distribution archives, but one can
simply include the source files (using, say, node.js) to use it without
building.
