I can give you one solution to this: you can set the svn:author
property yourself. You'd need to (temporarily, if you wish) install a
pre-revprop-change hook to allow revision property changes to take
place. See pre-revprop-change.tmpl in your hooks directory for an
example.

To start, you could use "svn log --quiet $REPO_URL" to get a list of
all revisions and their authors. Send this to a text editor where you
can rearrange the output into a series of "svn propset --revprop -r X
svn:author" lines. Then execute these lines.

For example, say my log output reads:

------------------------------------------------------------------------
r234 | ryan | 2006-11-24 00:05:26 -0600 (Fri, 24 Nov 2006)
------------------------------------------------------------------------
r208 | philip | 2006-10-03 16:18:47 -0500 (Tue, 03 Oct 2006)
------------------------------------------------------------------------

And I would like to change "ryan" to "rschmidt" and "philip" to
"pgollucci". I would send that log output to a text editor and munge
it (using a set of search/replace operations, possibly with regular
expressions) so that it looks like this:

svn propset --revprop -r 234 svn:author rschmidt $REPO_URL
svn propset --revprop -r 208 svn:author pgollucci $REPO_URL

where $REPO_URL is the actual URL to the repository. Then I would
execute this script.

Then you can remove the pre-revprop-change hook to prevent others
from being able to make such changes in the future.

Someone else's suggestion of dumping the repository, munging the
dumpfile and reloading it could work too, but I don't feel
comfortable munging dumpfiles, and besides, my solution works even if
others are actively using the repository; dealing with a dumpfile
means all write access to the repository needs to be disabled while
the transformation takes place.
