 * 随着项目增多,thrift IDL 生成代码的管理也越复杂。
 * 此工具用于生成 thrift 的代码,尽量使其脚本化,自动化。
 * 
 * 使用方法:
 * ./cthrift cms-exmaple ./cthrift.config.php
 * 
 * cthrift.config.php 是个配置文件:

<?php

return array(
    'thrift_command' => 'thrift --gen {gen} -out "{out}" "{idl}"',
    'projects' => array(
        'cms-exmaple' => array(
            'gen' => 'php',                       // 代码目标语言,用于 thrift 的 --gen 选项
            'out' => '/path/to/output',           // 代码输出目录,用于 thrift 的 --out 选项
            'idl_git_url' => 'https://git-url',   // IDL 是否使用了 git 管理,如果设置,则自动 pull,
                                                  // 例如 https://github.com/my/thrift-idl.git
            'idl_git_pre' => '/src/master',       // IDL 文件的 git URL 前缀。在本例中:
                                                  // 假设 idl_git_url 为 https://github.com/my/thrift-idl.git
                                                  // IDL 路径为 /path/to/cms.thrift,idl_root_path 为 /root/thrift/idl
                                                  // 则 git 的全路径为 https://github.com/my/thrift-idl/src/master/path/to/cms.thrift
                                                  // 对应的本地路径为 /root/thrift/idl/path/to/cms.thrift
            'idl_root_path' => '/path/to/idl',    // IDL 根目录,与 idls 拼接,如果有 git,此目录应当设置为 git 的根目录(含 .git 的目录)
            'idls' => array(  // IDL 所在的目录或文件
                '/path/to/idl/1',
                '/path/to/idl/2',
            ),
