 * Supports -I/usr/include -I=/usr/include -I /usr/include option
   argument specification
 * Supports multiple short options -aux
 * Supports all primitive go types (string, int{8..64}, uint{8..64},
   float)
 * Supports same option multiple times (can store in slice or last option
   counts)
 * Supports maps
 * Supports function callbacks
 * Supports namespaces for (nested) option groups
