Rake is a Make-like program implemented in Ruby. Tasks and dependencies are specified in standard Ruby syntax. Rake has the following features: * Rakefiles (rake's version of Makefiles) are completely defined in standard Ruby syntax. No XML files to edit. No quirky Makefile syntax to worry about (is that a tab or a space?) * Users can specify tasks with prerequisites. * Rake supports rule patterns to synthesize implicit tasks. * Flexible FileLists that act like arrays but know about manipulating file names and paths. * Supports parallel execution of tasks.

Thor is a toolkit for building powerful command-line interfaces.

Boson is a modular command/task framework. Thanks to its rich set of plugins, it differentiates itself from rake and thor by being usable from irb and the commandline, having optional automated views generated by hirb and allowing libraries to be written as plain ruby. Works with ruby >= 1.9.2
