def filename flags = nil
  flags ||= generate_flags
  # TODO: handle OS architecture properly by taking from context
  "#{flags['--name']}-#{flags['--version']}-#{flags['--epoch']}.x86_64.rpm"
end

#generate ⇒ Object

Calls FPM with the flags generated

def generate
  ::Albacore::CrossPlatformCmd.system 'fpm', generate_flags_flat
end

#generate_flags(overrides = {}) ⇒ Object

Generate flags for FPM - if you don’t want to execute directly with the object you can use this method to generate what you should give to FPM yourself
