ESLPod 在 iOS 的播客里面总是下载不了，于是做了这个工具用来自动 从 ESLPod 官网同步最新的音频文件到本地。
pip install https://github.com/graycarl/ESLGet/archive/master.zip
首选选择一个目录用来存放下载下来的音频文件，建议使用默认位置
~/Music/eslpods
然后直接运行 esldl 命令，并制定音频文件位置：
esl-get --path ~/SomePlace/here
esldl 会自动找到本地没有的新音频并下载下来：
# esl-get --path ~/SomePlace/here
Html load ok.
