The Sun Doc Check Doclet is an extension to the Javadoc tool It runs on source code and reviews documentation comments, generating an HTML report that identifies empty comments and other ommissions and irregularities in the documentation comments. The report displays the number of doc errors, categorizes problems according to severity, and suggests text to include. It can be instructed to ignore packages and classes using wildcard patterns. An included utility package contains functionality that scans a directory tree to generate a list of packages, as well as pattern-matching classes for filenames.
