DocPerl provides a Web-based interface to Perl's Plain Old Documentation (POD). It is a graphical, easy-to-use interface to POD, automatically listing all installed modules on the local host, and any other nominated directories containing Perl files. DocPerl can also display a summary of the APIs defined by files and the code of those files. It can search the POD documentation for module names and for functions defined in modules.
DocWiz allows you to easily add JavaDoc comments to your Java source code. With DocWiz, there's no need to tediously hand-format JavaDoc comments, adding tags and comment structures for each method. DocWiz provides a list of all the fields, methods, interfaces, and classes defined in a Java source file. You can click on any of these code elements to display a fill-in form for information about code elements. In addition, DocWiz shows you an icon for uncommented code segments.
The Docbkx Maven Plugin allows you to generate different types of output from DocBook sources.

Documancer is a programmer's documentation reader for Unix which has very fast fulltext searching. It has several advantages over using a Web browser or specialized format-specific viewers (such as info), namely unified access to all documentation formats and a GUI that is better-suited for documentation reading than a generic Web browser. It can display HTML manuals, info and man pages, CHM and DevHelp files, and remote WWW sites.
DogPerl is an offline Perl/Tk widget documentation resource. It includes an adjustable interface. Since it is a reference to detailed information about Tk widgets as they can be used in Perl, the program does not do much. It is an encyclopedia for Tk within Perl. However, font color, size, face, and style can be customized easily. Page background color, border size, and paragraph spacing are also customizable. The program illustrates the use of Perl/Tk.
DokuWiki is a standards-compliant, simple-to-use Wiki mainly aimed at creating documentation of any kind. It is targeted at developer teams, workgroups, and small companies. It has a simple but powerful syntax which makes sure the datafiles remain readable outside the Wiki, and eases the creation of structured texts. All data is stored in plain text files, so no database is needed
