const helpText=`super-tinypng 图片压缩命令行工具 - 处理输入目录中的图片并将压缩后的图片保存到指定的输出目录。

用法:
super-tinypng [选项]

选项:
--path <路径> 指定输入目录的路径。默认值为当前目录。
--out <路径> 指定输出目录的路径。默认值为输入目录下的 "output" 目录。

其他选项:
--help 显示帮助信息并退出。
--version 显示工具版本信息并退出。

示例用法:
1. 使用默认参数运行工具:
super-tinypng

2. 指定输入目录并将结果保存在默认的输出目录:
super-tinypng --path /path/to/input

3. 指定输入目录和输出目录的路径:
super-tinypng --path /path/to/input --out /path/to/output

注意:
- 输入目录中的文件将会被处理，处理结果将保存到输出目录中。
- 如果输出目录不存在，工具将尝试创建它。`;
