The GPL is the most widely used free software licence.It is a copyleft licence,which means that derivative work can only be distributed under the same licence terms as the original software.The software may be distributed with or without any charge.

GNU Lesser General Public Licence (LGPL): This licence allows developers to use and integrate a software component released under the LGPL into their software program,free or proprietary,without being governed by the terms of a strong copyleft licence.It means that they are not compelled to release the soure code of their components.

Eclipse Public Licence: This is a business-friendly free software licence.It includes weaker copyleft provisions than GNU General Public Licence (GPL).The EPL-licenced programs and modified versions can be used,modified,copied,and distributed.However,in some cases,the developer is obligated to release the changes.

Common Development and Distribution Licence(CDDL) This licence allows the CDDL licenced files to be combined with files licenced under other licences,whether open source or proprietary.It is incompatible with the GNU General Public Licence.
