more on installing the code - Decko

If you won't be developing the Wagn code, then you can just install trunk - e.g. in Unix, on the command line type:
svn checkout svn://rubyforge.org/var/svn/wagn/trunk wagn
(this will create a folder "wagn" and install Wagn there)
If you want to develop on Wagn, see our [RubyForge svn page][http://rubyforge.org/scm/?group_id=3630].
