Taskwarrior uses concepts and techniques described in Getting Things Done by David Allen, but is paradigm-agnostic in that it does not require users to adhere to any given life-management philosophy.
Taskwarrior's source code is freely available and can be compiled and run on a variety of architectures and operating systems, or installed using binaries obtained with common package management tools: (apt, Fink, yum, etc.) 
Taskwarrior comprises three main commands: add, list, and done. All other functionality – recurrences, tags, priorities, etc. – are optional.
