/*
    This minimal build system uses the Buntralino CLI's programmatic API.
    The calls are equivalent to the command-line interface.

    It also uses ESBuild to bundle all the code for Neutralino.js application
    into one file. See ESBuild documentation for more details and make it your own:
    https://esbuild.github.io/

    Use this file as a base for integrating with your existing build pipelines
    or expand this code with asynchronous tasks.
