      longDescription = ''
        The main idea behind babashka is to leverage Clojure in places where you
        would be using bash otherwise.

        As one user described it:

            I’m quite at home in Bash most of the time, but there’s a substantial
            grey area of things that are too complicated to be simple in bash, but
            too simple to be worth writing a clj/s script for. Babashka really
            seems to hit the sweet spot for those cases.

        Goals:

        - Low latency Clojure scripting alternative to JVM Clojure.
        - Easy installation: grab the self-contained binary and run. No JVM needed.
        - Familiarity and portability:
          - Scripts should be compatible with JVM Clojure as much as possible
          - Scripts should be platform-independent as much as possible. Babashka
            offers support for linux, macOS and Windows.
        - Allow interop with commonly used classes like java.io.File and System
        - Multi-threading support (pmap, future, core.async)
        - Batteries included (tools.cli, cheshire, ...)
        - Library support via popular tools like the clojure CLI
