设置创建属性
在项目目录（projects/infor96/）下创建文件 build.properties，最为简单的内容是：
# 项目名
propel.project = infor96
# 数据库类型
propel.database = mysql
设置运行时属性
在项目目录下创建 runtime-conf.xml 文件，内容为：
<?xml version="1.0" encoding="ISO-8859-1"?>
<config>
<log>
<ident>propel-infor96</ident>
<level>7</level>
</log>
<propel>
<datasources default="infor96">
<datasource id="infor96">
<adapter>mysql</adapter>
<connection>
<phptype>mysql</phptype>
<hostspec>localhost</hostspec>
<database>infor96</database>
<username>infor96</username>
<password>infor96</password>
</connection>
</datasource>
</datasources>
</propel>
</config>
可以看出，这个文件其实就是设置运行的时候需要用到的连接数据库参数，数据库名、用户、密码等。当生成 PHP 类文件时，这个文件会被自动转换成 projects/infor96/build/conf/runtime-conf.php，此文件路径在 Propel 初始化方法 Propel :: init() 中当参数传递。
生成 PHP 类文件
一切准备就绪，开始生成 PHP 类文件的工作了：
$ cd /usr/local/propel-generator
$ cp build.properties-sample build.properties
$ phing -Dproject=infor96
自动生成工作由 phing 来完成，如果没有安装 phing 的话，可以通过运行下边命令来安装：
pear install http://phing.info/pear/phing-current.tgz
在 phing 生成 PHP 类文件的过程中，可以看到很多输出：
