Usage: ./dtcw [option...] [task...]

You can use the same options and tasks as in underlying gradle.
Use "./dtcw tasks --group doctoolchain" to see available tasks.
Use "local", "sdk" or "docker" as first argument to force the use of a local, sdkman or docker install.

Examples:

  Download and install arc42 Template:
    ./dtcw downloadTemplate

  Generate PDF:
    ./dtcw generatePDF

  Generate HTML:
    ./dtcw generateHTML

  Publish HTML to Confluence:
