项目管理

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{}
