Acutally, for svn this is realtively trivial:

    svn ls -r ${rev} ${remote}

We have two packages in Buildroot that use svn, fis and open2300, so you
cn use them to test:

    $ svn ls -r 2892 http://svn.chezphil.org/utils/trunk
    Redirecting to URL 'https://svn.chezphil.org/utils/trunk':
    Makefile
    apexctl.cc
    [...]

Yann E. MORIN.
