OpenDocMan is a full featured Web-based document management system (DMS) designed to conform to ISO 17025/IEC. It features an automated installation script, custom themes, plugins, check-in/out, departmental access control, file moderation, fine grained user access control, and a great search function. Written in PHP, and utilizing MySQL for the backend, this project is useful for any company looking to keep their documentation in a centralized repository.
LyX is a document processor that encourages an approach to writing based on the structure of your documents, not their appearance. It is intended for people people who write and want their writing to look great without tinkering with formatting details, font attributes, or page boundaries. On screen, it looks like any word processor, but it uses the TeX engine for printed output and producing richly cross-referenced PDFs. It is stable and fully featured.
Cxref is a program that will produce documentation (in LaTeX, HTML, RTF or SGML) including cross-references from C program source code. It works for ANSI C, including most gcc extensions. The documentation for the program is produced from comments in the code that are appropriately formatted. The cross referencing comes from the code itself and requires no extra work.
Doxygen is a cross-platform, JavaDoc-like documentation system for C++, C, Objective-C, C#, Java, IDL, Python, PHP, VHDL, and Fortran. Doxygen can be used to generate an on-line class browser (in HTML) and/or an off-line reference manual (in LaTeX or RTF) from a set of source files. Doxygen can also be configured to extract the code-structure from undocumented source files. This includes dependency graphs, class diagrams and hyperlinked source code. This type of information can be very useful to quickly find your way in large source distributions.
GNU TeXmacs is a free wysiwyw (what you see is what you want) editing platform with special features for scientists. The software aims to provide a unified and user friendly framework for editing structured documents with different types of content: text, mathematics, graphics, interactive content. TeXmacs can also be used as an interface to many external systems for computer algebra, numerical analysis, and statistics. New presentation styles can be written by the user and new features can be added to the editor using Scheme.
UMLet is a lightweight tool for rapidly drawing UML diagrams, with a sound and pop-up-free user interface. UMLet lets you draw diagram sketches quickly, teach UML with a simple user interface, and export diagrams to SVG, JPG, PDF, and LaTeX-friendly EPS. It features a fast, text-based way of editing UML elements.
Foswiki is wiki software, supporting the editing of Web pages in an ordinary Web browser by end users. What makes Foswiki special is that it supports the embedding of active and passive macros that enhance the page content (e.g. with global or dynamic information) and allow end-users to build applications that store and process data in a structured manner.
Thot takes as input text in a wiki-like format and outputs results for different formats: HTML, Latex, DocBook, and PDF. Although delivered with only one input language (Dokuwiki format), Thot is very versatile and easy to extend. For example, the initial version allows you to embed a document description from different entities: source language, GraphViz DOT graphs, Latex math, etc.
gjots lets you organize text notes in a convenient, hierarchical way. It can be used for notes, jottings, bits and pieces, recipes, and even PINs and passwords, using encryption. It can also be used to "mind-map" larger compositions like manuals, Web pages, articles, etc. It is a bit like the KDE program "kjots", but uses the GTK library and supports a hierarchy of folders. Files can be output to HTML with an automatic table of contents or to docbook XML. Encryption is supported with ccrypt(1), gpg(1), and openssl(1), so that musings can be kept private.
