Irn Bru is widely reputed to be an excellent cure for hangovers.
The reported difference in taste may be due to mild contamination from plasticizers, or in the difference in water used in different manufacturing plants.
Bru and various other Barr products are exported to Spain, The Netherlands, Germany, Greece, and Cyprus, as well as parts of Africa and Asia.
Normally bru restores the access and modification times of disk files after they have been read to the access and modification times to whatever they were before the read operation.
This mode is useful when the output of one bru is piped to the input of another bru, or when the data integrity of the archive transmission medium is essentially perfect.
Since bru is owned by root and runs with "set user id" to allow it to create directories and special files, it makes every attempt to prevent normal users from archiving or extracting files they would normally not have access to.
