All the subdirectories of this directory contain code from the OpenCores project, checked out directly from the OpenCores CVS server. You can update any directory to the latest OpenCores code by doing "cvs up" in that. This is not recommended unless you know what you are doing. Each directory contains its own copyright and licensing information. We believe that we have the right to distribute all of these files in the form in which we provide them. If this is not the case, please notify Matt Ettus, matt@ettus.com.
