27revdiff FILE OLD NEW
28
29Get a diff of FILE between revisions OLD and NEW. Store the
30diff in a file named FILE-OLD-NEW.diff.
31
32If OLD is `-' use FILE's current revision for OLD. If OLD is
33`-<number>', use the Nth revision before the current one for OLD.
34
35If NEW is +<number> or -<number>, build diffs between revisions OLD
36and OLD +/- <number>.
37
38Examples:
39
40revdiff FILE - -1 get the latest change of FILE
41revdiff FILE -1 +1 also gets the latest change of FILE
42revdiff FILE 1.500 +2 get diffs 1.500-1.501 and 1.501-1.502.
