+Gremlin-Console 是由 Tinkerpop 自己开发的一个交互式客户端，用户可以使用该客户端对 Graph 做各种操作，主要有两种使用模式：
-- 单机离线调用模式；
-- Client/Server请求模式；
+- 单机离线调用模式
+- Client/Server 请求模式
### 1 单机离线调用模式
-由于lib目录下已经包含了HugeCore的jar包，且HugeGraph已经作为插件注册到Console中，用户可以直接写groovy脚本调用HugeGraph-Core的代码，然后交由Gremlin-Console内的解析引擎执行，就能在不启动Server的情况下操作图。
+由于 lib 目录下已经包含了 HugeCore 的 jar 包，且 HugeGraph 已经作为插件注册到 Console 中，用户可以直接写
groovy 脚本调用 HugeGraph-Core 的代码，然后交由 Gremlin-Console 内的解析引擎执行，就能在不启动 Server
的情况下操作图。
这种模式便于用户快速上手体验，但是不适合大量数据插入和查询的场景。下面给一个示例：
-在script目录下有一个示例脚本：example.groovy
