开放式源码的软件.
源码是可供人查看,参考,学习的.相对的,一般商业软件的源码是看不到的.一般开放式源码的软件也同时是免费的（源码都给你看了,你自己编译后就可用了）.
The free software movement was launched in 1983.In 1998,a group of individuals advocated that the term free software be replaced by open source software (OSS) as an expression which is less ambiguous and more comfortable for the corporate world[5].Software developers may want to publish their software with an open source license,so that anybody may also develop the same software or understand how it works.Open source software generally allows anyone to make a new version of the software,port it to new operating systems and processor architectures,share it with others or market it.The aim of open source is to let the product be more understandable,modifiable,duplicatable,reliable or simply accessible,while it is still marketable.
The Open Source Definition,notably,presents an open source philosophy,and further defines a boundary on the usage,modification and redistribution of open source software.Software licenses grant rights to users which would otherwise be prohibited by copyright.These include rights on usage,modification and redistribution.Several open source software licenses have qualified within the boundary of the Open Source Definition.The most prominent example is the popular GNU General Public License (GPL).While open source presents a way to broadly make the sources of a product publicly accessible,the open source licenses allow the authors to fine tune such access.
