This is a simple wrapper over SVN 1.7 command, but should work on older version as well, envoltura is implemented in Java/Swing and tested over xubuntu 12.10 box.
I actively use this client myself along with my friends but only very limited subset of the feature as I mostly prefer to use command-line interface.
This client was created to simplify commit of multiple files and provide a simpler interface for code diffing - currently the envoltura hardcoded invoked 'meld' when ever svn diff is executed.
I would encourage you to raise a ticket request if you are specifically looking for a feature.
