I just added yet another command line option, --backup, a boolean off by 
default, that causes the repository to be backup immediately after Chandler 
opens the repository.

This way, you can backup your repository before doing surgery on it
with --undo.

The destination of the backup is emitted to chandler.log. That file is in 
your profile directory whose hiding place is described here:
   http://wiki.osafoundation.org/twiki/bin/view/Projects/ProfileDirectory

You can also use -e to get repository log message emitted to stderr.

For example:  rc --backup --undo check -e
   1. backs up the repository
   2. then runs check() and undo() until check() passes

To restore a repository from a backup:  rc --restore <dbHome>
   where <dbHome> is the path emitted during --backup
