These concerns are not unique to public * domain software. Most large, established open-source projects have a * Contributor License Agreement (CLA) process, of varying degrees of formality. * * Please add yourself to the list below before contributing. * Thanks. * * -- * * "I dedicate any and all copyright interest in this software to the three * licensing terms listed above.
