To find the version of the subversion REPOSITORY you can:
- Look to the repository on the web and on the bottom of the page it will say something like:
“Powered by Subversion version 1.5.2 (r32768).” - From the command line: <insert curl, grep oneliner here>
If not displayed, view source of the page
<svn version="1.6.13 (r1002816)" href="http://subversion.tigris.org/">
Now for the subversion CLIENT:
svn --version
will suffice
