svn backup via rake.. easier way to obtain lastest rev?

[Simon Strandgaard]

I have made a small script that makes a backup of
a subversion repository.. with outputfiles formatted as:
backup20050722_rev68.gz

But I wonder if there is a smarter way to determine what
the last revision?

require 'open3'

task :svnbackup do
=09repos =3D '/Users/simonstrandgaard/code/svnrepos'

Hmm.. my svnadmin does not support 'youngest'..
my svn+svnadmin versions is 1.1.3 (r12730).
