@echo off

@rem This script will install git (if not found on the PATH variable)
@rem  using micromamba (an 8mb static-linked single-file binary, conda replacement).
@rem For users who already have git, this step will be skipped.

@rem Next, it'll download the project's source code.
@rem Then it will download a self-contained, standalone Python and unpack it.
@rem Finally, it'll create the Python virtual environment and preload the models.

@rem This enables a user to install this project without manually installing git or Python
