pixi.toml

# Pixi is a package management tool for developers.
# Before running a task, pixi ensures that all listed dependencies are installed first.
#
# Pixi is not required for rerun, but it is a convenient way to install the
# dependencies required for this example.
#
# https://prefix.dev/docs/pixi/overview
#
# Use `pixi task list` to list the available tasks,
# and `pixi run TASK` to run it (e.g. `pixi run example`).
