Getting the latest version of cv2pdb from the subversion repository
If you have subversion installed on your system you can checkout the latest version from the repository. Open up a terminal, go to the directory where you want cv2pdb to be after checkout, and run the command:
svn co http://svn.dsource.org/projects/cv2pdb/trunk
The cv2pdb svn repository is not always guaranteed to be compilable. It is the bleeding edge, and might be going over some dramatic changes at any random time.
You can then use the forum to ask the project admin to give you write access to the cv2pdb repository, if you want to start improving cv2pdb.
