udkundoku.load() is an alias for udkanbun.load() of UD-Kanbun. udkundoku.translate() is a transcriptive converter from Classical Chinese (under Universal Dependencies of UD-Kanbun) into Modern Japanese (under Universal Dependencies of UniDic2UD). udkundoku.reorder() is called to rearrange Classical Chinese into Japanese word-order inside udkundoku.translate(). to_tree() and to_svg() are borrowed from those of UD-Kanbun.

You can simply use udkundoku on the command line:

echo 不入虎穴不得虎子 | udkundoku -j

HTTP-server usage

python -m udkundoku.server 5000

Try to connect http://127.0.0.1:5000 with your local browser. Input a Classical Chinese sentence there and push 解析-button (at least) three times.
