How to build a custom lib with holidays of your own

Generate a new clojure deps project:

curl -LO https://raw.githubusercontent.com/luciolucio/holi/0.17.0/new-holi-project.sh
bash new-holi-project.sh

Follow the instructions in its README to create holiday calendar files of your own and generate a jar. It will expose the same API as holi but your holidays will be available instead.
