// Procedure
// Save options in fields
// Each type, such as Include, User etc is own type
// Each type inherits interface
// This interface has methods such as:
// - CheckIsUser()
// For user, this checks if the user is listed in passwd
// For include, this includes the file and parses it and validates it
//

// Parse content manually as the /etc/aliases file is so simple
