• specification = [ base₁ , ..., base_n ]
• base = (position, packages)
• position = (x,y)
• packages = [ package₁, ..., package_n ]
• package = Mk { uid=number, dest=position, weight= number }

• Spaces and line breaks can be inserted between parts.
• All numbers should be nonnegative.
• Every package should have a unique uid number.
• The base positions should be marked as bases on the map.
