Okay, let's say you have two dump files, from previously disjoint repositories
that you want to merge:

/trunk/a/
r1 @ 2004-01-01
r2 @ 2004-01-02
r3 @ 2004-01-03

/trunk/b/
r1 @ 2004-01-01
r2 @ 2004-01-02
r3 @ 2004-01-03

You load them together and get

/trunk/a/ and /trunk/b/
r1 @ 2004-01-01
r2 @ 2004-01-02
r3 @ 2004-01-03
r4 @ 2004-01-01
r5 @ 2004-01-02
r6 @ 2004-01-03

You then do "svn log -r {2004-01-02:HEAD} .../trunk"

The date-revision mapper will determine that r2 is the revision
associated with 2004-01-02, and will then show r2, r3, r4, r5, and r6
in the output. Note that r4 should not be shown, since it is before
2004-01-02.
