 * that a supply mechanism has to be added in a derived contract using {_mint}.\r
 * For a generic mechanism see {ERC20PresetMinterPauser}.\r
 *\r
 * TIP: For a detailed writeup see our guide\r
 * https://forum.zeppelin.solutions/t/how-to-implement-erc20-supply-mechanisms/226[How\r
 * to implement supply mechanisms].\r
 *\r
 * We have followed general OpenZeppelin Contracts guidelines: functions revert\r
 * instead returning `false` on failure. This behavior is nonetheless\r
 * conventional and does not conflict with the expectations of ERC20\r
 * applications.\r
 *\r
 * Additionally, an {Approval} event is emitted on calls to {transferFrom}.\r
 * This allows applications to reconstruct the allowance for all accounts just\r
 * by listening to said events. Other implementations of the EIP may not emit\r
 * these events, as it isn't required by the specification.\r
 *\r
 * Finally, the non-standard {decreaseAllowance} and {increaseAllowance}\r
 * functions have been added to mitigate the well-known issues around setting\r
 * allowances. See {IERC20-approve}.\r
