GNU

GNU 操作系统 - 自由软件基金会（FSF）

GNU 工程开始于一九八四年，旨在发展一个类似 Unix ，且为自由软件的完整操作系统： GNU 系统。（GNU 是由“GNU's Not Unix”所递回定义出的首字母缩写语；它的发音为“guh-NEW”）。各种使用 Linux 作为内核的 GNU 操作系统正被广泛地使用著；虽然这些系统通常被称作为“Linux”，但是它们应该更精确地被称为 GNU/Linux 系统。

这里同样也是自由软件基金会的网站（FSF）。 FSF 是 GNU 工程的主要赞助组织。 FSF 只由公司或作出转让的基金会处收到很少的资金。我们依赖来自於像您这样，支持 FSF 保存、保护以及促进「使用、研究、复制、修改和重新散布电脑软件」，并且保卫著自由软件使用者的权利的任务的个人的支持。去年，我们的运作资金超过百分之六十七来自於个人的捐赠。持续进行的支持是我们可以继续我们的工作的主要方式。
