It also is an authoring system with unique support for literate programming and reproducible research.
Org is implemented on top of Outline mode, which makes it possible to keep the content of large files well structured.
Project planning and task management makes use of metadata which is part of an outline node.
Based on this data, specific entries can be extracted in queries and create dynamic agenda views that also integrate the Emacs calendar and diary.Org can be used to implement many different project planning schemes, such as David Allen's GTD system.Org files can serve as a single source authoring system with export to many different formats such as HTML, La Te X, Open Document, and Markdown.New export backends can be derived from existing ones, or defined from scratch.Org files can include source code blocks, which makes Org uniquely suited for authoring technical documents with code examples.Org source code blocks are fully functional; they can be evaluated in place and their results can be captured in the file.
