    ============================== Description ==============================

    This build file offers an alternative method to build PlantUML.

    While PlantUML is typically built using Gradle, this Ant build script
    provides a fallback option for those who prefer or only have access to
    Ant.

    Usage:
    To build using this file, navigate to the directory containing this
    build.xml and run "ant" in the command line. For more detailed build
    instructions and requirements, refer to:
    https://github.com/plantuml/plantuml/blob/master/docs/BUILDING.md
