 1. Why Free Software Needs Free Documentation {#why-free-software-needs-freedocumentation .chapter}

+自由的操作系统最大的不足并非是软件——而是缺乏可以收录其中的优秀自由手册。我们很多重要的程序没有完善的手册。文档是任何软件包的重要组成部分；当一个重要的自由软件包发布，却没有附带自由的手册，这会是一个严重的缺陷。现在存在很多这样的缺陷。

 O’Reilly Associates, which published them with restrictive terms—no
 copying, no modification, source files not available—which exclude them

 matter, they don’t stop the conscientious programmer from adapting the

 We can also encourage commercial publishers to sell free, copylefted
 manuals instead of proprietary ones.[(2)](#FOOT2) One way you can help
 this is to check the distribution terms of a manual before you buy it,
 and prefer copylefted manuals to noncopylefted ones.
