Zeus engine setup.

custom_plan.rb

require 'zeus/rails'

ROOT_PATH = File.expand_path(Dir.pwd)
ENV_PATH  = File.expand_path('spec/dummy/config/environment',  ROOT_PATH)
BOOT_PATH = File.expand_path('spec/dummy/config/boot',  ROOT_PATH)
APP_PATH  = File.expand_path('spec/dummy/config/application',  ROOT_PATH)
ENGINE_ROOT = File.expand_path(Dir.pwd)
ENGINE_PATH = File.expand_path('lib/my_engine/engine', ENGINE_ROOT)

class CustomPlan < Zeus::Rails
end

Zeus.plan = CustomPlan.new

Works for test and generate, but oddly enough, not for destroy:

jaiken@firefly➜ git:(master) git st
# On branch master
nothing to commit, working directory clean
jaiken@firefly➜ git:(master) zeus generate model Foo
      invoke  active_record
      create    db/migrate/20131030000225_create_foos.rb
      create    app/models/foo.rb
      invoke    rspec
      create      spec/models/foo_spec.rb
      invoke      factory_girl
      create        spec/factories/foos.rb
jaiken@firefly➜ git:(master) ✗ zeus destroy model Foo
      invoke  active_record
      remove    migration.rb
      remove    app/models/foo.rb
      invoke    rspec
      remove      spec/models/foo_spec.rb
      invoke      factory_girl
      remove        spec/factories/foos.rb
jaiken@firefly➜ git:(master) ✗ git st
# On branch master
# Untracked files:
#   (use "git add <file>..." to include in what will be committed)
#
#   app/models/foo.rb
#   db/migrate/20131030000225_create_foos.rb
#   spec/factories/foos.rb
#   spec/models/foo_spec.rb

Still, got me alot zeusy than I was before, thanks! :)
