Failing some already-built tool for this, you could use "svn diff -
r'{DATE1:DATE2}'" to get the diff between the last revision before
DATE1* and the last revision before DATE2, and then parse it, for
example looking at the number of lines beginning with "+" (added
lines) and "-" (deleted lines).

First be sure, however, that you really want to do this; many
consider affected-lines-of-code counts to be a pointless metric to
track. The example I like to give:

http://www.folklore.org/StoryView.py?
project=Macintosh&story=Negative_2000_Lines_Of_Code.txt&topic=Management
&sortOrder=Sort%20by%20Date

It can perhaps be useful as a very general indicator of where things
are happening in a project.

*Note that this will include the changes for one additional revision
that you did not want, at the beginning of the range. See the box "Is
Subversion a Day Early?" on this page:
