-## Caesium 命令行工具
-###### caesium-clt - v0.21.0
-
-###### 依赖
-* [Rust](https://www.rust-lang.org/tools/install)
-----------
-
-###### 编译
-`cargo build --release`
-
-----------
-
-###### 命令行参数
-- `-q, --quality [value]` {Required}  
-  设置图像质量，值越高，图像越好。当值为 0 将 _无损_ 压缩图片，不会修改原图，但压缩得很少。  
-  可选范围为 [0, 100] ，有损压缩的常见值为 `80` 。
-- `-e, --exif`  
-  压缩过程中保留 JPEG 元数据信息，文件大小将会略高。
-- `-o, --output [value]` {Required}  
-  压缩文件的输出文件夹的路径，如果和输入文件夹相同将覆盖原文件。
-- `-R, --recursive`  
-  如果输入是文件夹，caesiumclt 将会递归扫描每个子文件夹以搜索图像。  
-  请注意，这最终可能会有大量要压缩的文件，应谨慎使用。
-- `-S, --keep-structure`  
-  如果输入是文件夹，并且设置了 `-R` 选项，caesiumclt 将保持原始文件夹结构地压缩所有文件。
-- `-O, --overwrite`  
-  设置覆盖策略：`all` 将覆盖任何现有文件，`prompt` 将在每次覆盖前询问，`bigger` 将仅覆盖更大的文件，而 `none` 将静默跳过现有文件。
-- `-d, --dry-run`  
-  如果设置了此选项，则不会压缩任何文件，而只是模拟整个过程。   
-  用于检查是否所有文件都将会被正确处理。
-- `-Q, --quiet`  
-  抑制所有的输出，但 libcaesium 库的输出仍将被输出。
-- `-h, --help`  
-  显示命令行参数的摘要，就像您正在阅读的这个。
-- `-v, --version`  
-  打印当前的 caesiumclt 版本。
-

-###### 使用示例
-
-将位于 `home` 目录中的 `image1.jpg` 无损压缩到名为 `output` 的文件夹中：
-```
-$ caesiumclt -q 0 -o ~/output/ ~/image.jpg
-```
-
-将位于 `home` 目录中的 `image1.jpg` 压缩到名为 `output` 的文件夹中，且有损压缩和质量设置为 `80`：
-```
-$ caesiumclt -q 80 -o ~/output/ ~/image.jpg
-```
-
-将位于 `home` 目录中的 `image1.jpg` 无损压缩到名为 `output` 的文件夹中，且保留 EXIF 元数据：
-```
-$ caesiumclt -q 0 -e -o ~/output/ ~/image.jpg
-```
-
-将位于 `home` 目录中的 `Pictures` 文件夹和其子文件夹无损压缩到名为 `output` 的文件夹中：
-```
-$ caesiumclt -q 0 -R -o ~/output/ ~/Pictures
-```
-
-将位于 `home` 目录中的 `Pictures` 文件夹和其子文件夹无损压缩到名为 `output` 的文件夹中，且保留输入文件夹的结构：
-```
-$ caesiumclt -q 0 -RS -o ~/output/ ~/Pictures
-```
