<p>I'm looking for a <strong>subversion web client</strong> ala <a href="http://search.cpan.org/dist/SVN-Web/" rel="nofollow noreferrer">SVN::Web</a> but with a very specific feature I've always thought would be quite useful.</p>

<p>What I want is the ability to find <strong>which revision was responsible for a certain line</strong> (or lines) in a text file.  A way to do this via the web would be fantastic.</p>

<p>Anybody know of such a tool?</p>

I thought that SVN had the 'blame' function that could do something similar to that. I am taking a stab in the dark though.  Hold on while I take a quick look through the interwebs.
You bet.  Check
this
out.  (I use subclipse btw)
This implies that most web SVN interfaces will have this feature because it is not anything really special.
