* @dev Provides information about the current execution context, including the |
|
* sender of the transaction and its data. While these are generally available |
|
* via msg.sender and msg.data, they should not be accessed in such a direct |
|
* manner, since when dealing with meta-transactions the account sending and |
|
* paying for execution may not be the actual sender (as far as an application |
|
* is concerned). |
|
* |
|
* This contract is only required for intermediate, library-like contracts. |
