+  # 文件组成
+
+    # zendata以yaml格式的文件来定义各个字段的格式。
+    # yaml文件整体由文件说明和字段定义两部分组成。
+
+  # 文件说明
+
+    # title:   标题，可以用简短的文字概要描述该文件定义的数据类型。
+    # desc:    描述，可以用多行文本来详细描述该文件定义的数据类型，非必选项。
+    # author:  作者，非必选项。
+    # version：版本号，非必选项。
+
+  # 字段列表
+
+    # 字段定义部分都放在fields这个定义里面。
+    # 一个yaml文件可以包含一个或者多个字段。
+    # 字段列表以-field定义开始。
+    # 一个字段可以通过fields属性定义它的子字段。
+
+  # 字段定义
+
+    # field：    字段名，仅支持英文、数字、下换线和.
+    # range：    列表范围，最重要的定义。
+    # loop：     循环次数，可以定义某一字段循环多少次。
+    # loopfix：  每一次循环时的连接符。
+
+    # format:    支持格式化输出。   
+
+    # prefix：   该字段的前缀。
+    # postfix：  该字段的后缀。
+
+    # length：   该字段的长度。如果不通过分隔符区分，则需要指定字段长度，单位是字节。
+    # leftpad：  左填充的字符。如果长度不够，可指定左填充的字符。默认是以空格左填充。
+    # rightpad： 右填充的字符。如果长度不够，可指定右填充的字符。
+
+    # config:    可以引用另外一个文件里面的定义。
+
+    # from：     引用某一个定义文件。
+    # use：      使用被引用文件中定义的若干实例。all代表使用所有。
+    # select：   如果引用的文件是excel表，可以查询里面的某一个字段。
+    # where:     如果引用的文件是excel表，可以使用查询条件。
+  
+  # range定义
+
+    # 使用逗号连接不同的元素。比如 range: 1,2,3
+    # 元素也可以是一个区间。比如 range:1-10, A-Z
+    # 区间可以通过冒号:来指定步长。比如 range:1-10:2。
+    # 步长可以是小数。比如 range: 1-10:0.1
+    # 区间可以通过R来指定随机。比如 range: 1-10:R，随机和步长只能二选一。
+    # 可以通过一个文件来指定列表。比如range: list.txt。文件名是相对路径时，以配置文件为基准计算。
+    # 可以通过{n}的方式来重复某一个元素。比如 range: user1{100},user2{100}
+    # 如果区间或者几个元素需要重复，需要用[]括起来。比如 range: [user1,user2,user3]{100}
