When archiving a repository there is no way to specify a file as output. This patch adds a new option "--output" that redirects the output to a file instead of stdout. Signed-off-by: Carlos Manuel Duclos Vergara <redacted> Signed-off-by: Junio C Hamano <redacted> --- * I've fixed it up slightly; especially the tests, which were not making sure the results match what are expected.
