Provides self-contained file utility functions including a robust Unzip implementation that properly handles directories and files, ReadLines for reading file contents, Exists for file existence checks, and GetCurrentPath for locating the executable directory. Zero internal dependencies make this highly reusable.

Contains the GetJavaHome function that locates the Java home directory by finding javac.exe in a JDK temporary directory. This isolated utility has zero internal dependencies and demonstrates a clean approach to Java environment detection that could be reused in any Java-related tooling.

Implements web utilities including SetProxy for proxy configuration, Download with progress bar functionality, GetJDK for JDK-specific downloads, and helper functions for retrieving URL content. Only depends on an external progress bar package, making it mostly self-contained and extractable for HTTP download needs in other projects.

Defines a clean jdkProvider interface and demonstrates a plugin architecture for JDK version sources (Adoptium, Azul, original index). The ConfiguredFunctions shows how to compose providers. This pattern is easily reusable for any version management system by defining a simple version struct and implementing the Fetch method.
