为了养成良好的习惯，我们把 ConTeXt 文档拆分到几个单独的
.tex 文件中，这样维护起来比较方便。
首先是主文档 product.tex[73]，生成 PDF 只要编译此文件即可
%%%%%此文件使用 product 环境，起始声明 \startproduct{} %%%导言区使用 \environment 载入文件 %载入样式文件 style.tex \environment style %载入词汇定义文件 gloss.tex \environment gloss %%%正文起始 \starttext %%%正文区使用 \component 载入文件 %封面 cover.tex \component cover %目录 \title{目录} \placecontent %%正文内容 %载入章节 1.tex 2.tex 3.tex \component 1 \component 2 \component 3 %%%正文结束 \stoptext %%%%% product 环境结束声明 \stopproduct
在导言区载入的文件，要使用 environment 环境，例如样式定义文件 style.tex
\startenvironment{}
