You can look at what Insurrection does for the RSS feeds. It is in the
http://svn.sinz.com:8000/svn/Web/trunk/rss.cgi

It is "stupid" as some of the comments state, but it handles getting only
a subset of the log for RSS using a date range. Now, I don't use XSLT
in this case since most RSS readers do not support that, but that is a minor
nit. (I really should use XSLT to be completely correct, but RSS is so
simple that the perl regexp trick worked just fine.)

Yes the limit would be nice in case there are more than 20 (or whatever limit
is needed) entries within that date range.

I also have the date range start at the newest entry in that part of the
repository. This way if no changes over the weekend, you still get the
last n-days of changes rather than missing those 2 days.

You can try the RSS feed here: http://svn.sinz.com:8000/svn/Web/trunk/?Insurrection=rss
