Rube -- Slightly smarter erb front-end

Rube allows you to apply erb to templates, interspersed with other ruby code, either as inline source or 	
as ruby files (e.g. requires). Rube can be invoked from the command line as a command in the form:

  rube [options] task ...

• Can be invoked from command line or via the Ruby API from within a Ruby script

• Can process inline ruby code, ruby libraries, and erb templates

• Information is persistent across tasks: e.g. subsequent templates can refer to results of previous tasks

Rube can be invoked from the command line as a command in the form:

  rube [options] task ...

or as part of a ruby script, as in:

  require 'rube'
  rube = Rube.new
  rube.add_task(:require, 'active_record')
  rube.add_task(:template, 'foo')
  rube.generate

In either case, tasks may be erb templates, ruby files, or inline ruby code. Each of the tasks is 
performed in the order specified and variables, constants etc. are preserved across tasks (including 
local variables) so that subsequent tasks can refer to the the results of earlier tasks. This makes it 
simpler to use erb templates against arbitrary data. For instance:

  rube -r active_support -r yaml -e "document=YAML.load(IO.read('document.yml))" --trim 2 --stdin convert_to_textile.erb

would process the template on stdin followed by the template in convert_to_textile.erb, having already 
loaded the active_support and yaml libraries, and having loaded the YAML file document.yml and parsed it 
into a Ruby variable named document, where the information could easily be referred to in the template. 
This all would be done at erb trim level 2.

See rdoc or source for more information, or type the command:

  rube --help
