2021-10-001-beta Initial Beta Release

This is the initial beta release. All comments and issues are welcome. Please open an issue if you encounter problems, have questions, or have a feature request. Also please feel free to submit a pull request. Binaries for Windows, Mac, and Linux (x86) are provided below. The binaries are stand-alone executables that contain the dart runtime, no need for external dependencies. The Mac and Linux binaries have been compiled and tested on virtual machines. For other architectures, you will need to compile yourself - see the Readme file for details. Detailed usage instructions are in the Readme.
