WordPress:License
WordPress Licensing[ ]
WordPress 许可[ ]
Like most software, WordPress is distributed under a license, which means there are certain things that you are legally permitted (and not permitted) to do with WordPress software and source code. WordPress is distributed under a license called the GNU General Public License, a very popular license in the open source industry. If that doesn't ring a bell, read on.
与大多数软件相似，WordPress是在某个许可条件下，发行的，意思是你能够合法地处理WordPress软件和源代码的某个方面（但是某些方面是不能处理的）。WordPress的许可证称为GNU General Public License|一般公共许可证，开放源码行业中非常流行的许可。如果你还不了解，请继续阅读。
About the GPL[ ]
关于 GPL[ ]
The GNU General Public License, or GPL, is an open source license. Open source doesn't just mean that you can view the source code — it has political and philosophical implications as well. Open source, or "Free Software", means you are free to modify and redistribute the source code under certain conditions. Free doesn't refer to the price, it refers to freedom. The difference between the two meanings of free is often characterized as "Free as in speech vs. free as in beer." The GPL is free as in speech.
GNU一般公共许可，或者GPL，是个开放源码许可。开放源码并不是指你可以浏览源代码&mdash；开放源码也有政治哲学方面的关联。开放源码或者"免费软件"，指的是在某些条件下，你可以自由地更改和重新布置源代码。Free（自由的）并不是指的是价格方面，而是指的是自由。free（自由的，免费的）的两个不同的意思，通常可以在"Free as in speech（自由言论）和free as in beer"（免费啤酒）中体现出来。GPL中的free（自由的），就如free as in speech（自由言论）中的free（自由的）的意思。
Why We Chose the GPL[ ]
为什么我们选择 GPL[ ]
The reasons for WordPress releasing under the GPL are both practical and idealistic. WordPress was born of the very freedom mentioned earlier. The predecessor to the WordPress project, b2/cafelog, was also an open source project.
WordPress在GPL的条件下，发行是因为既理想又实用。前面已经提及，WordPress产生之初，即有很大的自由度。WordPress软件继承的b2/cafelog，也是一个开放源码软件。
