Tines is a console-based outliner, planner, and notebook application that serves as a fork of the unmaintained hnb outliner. The project supports organizing various types of hierarchical data such as to-do lists, addresses, notes, and brainstorming materials, with export capabilities including Markdown and Groff formats via XSLT processing. Built for Unix-like systems using curses/ncurses, the application is written in C and supports multiple file formats including OPML and XML, with features like search, cut/paste, priorities, and mouse navigation. The project is maintained by Larry Kollar and documented through a wiki and included manpages.
