rake
RAKE(1) Ruby Programmers Reference Guide RAKE(1)NAME
rake -- Ruby Make
SYNOPSIS
rake [--f Rakefile] [--version] [-CGNPgnqstv] [-D [PATTERN]] [-E CODE] [-I LIBDIR] [-R RAKELIBDIR] [-T [PATTERN]] [-e CODE] [-p CODE]
[-r MODULE] [--rules] [variable=value] target ...
DESCRIPTION
Rake is a simple ruby(1) build program with capabilities similar to the regular make(1) command.
Rake has the following features:
o 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?).
o Users can specify tasks with prerequisites.
o Rake supports rule patterns to synthesize implicit tasks.
o Flexible FileLists that act like arrays but know about manipulating file names and paths.
o A library of prepackaged tasks to make building rakefiles easier.
OPTIONS --version Display the program version.

--classic-namespace
Put Task and FileTask in the top level namespace
