Since software comprehension is the most expensive part of software maintenance, redocumentation is the key to software maintainability. The paper describes the process and the tools of incremental redocumentation where the comprehension of the software is recorded in hypertext, in the style of the World Wide Web. The paper describes the tools which support redocumentation, and gives several examples.
