Copies specified files into appliance.
There are two types of paths:
remote - starting with http:// or https:// or ftp://
local - all other.
Please use relative paths. Relative means relative to the appliance definition file. Using absolute paths will cause creating whole directory structure in appliance, which is most probably not exactly what you want.
