-Rake is a Make-like program implemented in Ruby. Tasks and dependencies are

-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.
