## When (not) to use workspaces
In a workspace, each package defines its own `pyproject.toml`, but the workspace shares a single
lockfile, ensuring that the workspace operates with a consistent set of dependencies.

This seems vaguely conflicting with the above

distinct packages with independent dependencies.

Maybe we should say "independent requirements" above? or "consistent set of dependency versions" here? I'm not sure.

has a performance-critical subroutine implemented in a native language.
As such, `uv lock` operates on the entire workspace at once, while `uv run` and `uv sync` operate on
the workspace root by default, though both accept a `--package` argument, allowing you to run a
command _in_ any workspace member _from_ any workspace directory.

Perhaps "in a particular workspace member"?

Currently, workspace don't properly support different members having different `requires-python`
values, we apply the highest of all `requires-python` lower bounds to the entire workspace. You need
to use a `uv pip` to install individual member in an older virtual environment.
To create a workspace, add a `tool.uv.workspace` table to a `pyproject.toml`, which will implicitly

We could also suggest in a !!! tip that uv init child in a project will do this for you.

Every directory included by the `members` globs (and not excluded by the `exclude` globs) must
contain a `pyproject.toml` file; in other words, every member must be a valid Python package.

If they do not, what happens? Do we ignore them? Do we fail?


There a two main workspace structures: A **root package with helpers** and a **flat workspace**.
Within a workspace, dependencies on workspace members are facilitated via `tool.uv.sources`, as in:

We should link to the dependency sources concept document.

### Release Notes

<details>
<summary>astral-sh/uv (astral-sh/uv)</summary>

### [`v0.3.0`](https://github.com/astral-sh/uv/blob/HEAD/CHANGELOG.md#030)

[Compare Source](astral-sh/uv@0.2.37...0.3.0)

This release introduces the uv [project](https://docs.astral.sh/uv/guides/projects/),
[tool](https://docs.astral.sh/uv/guides/tools/),
[script](https://docs.astral.sh/uv/guides/scripts/), and
[python](https://docs.astral.sh/uv/guides/install-python/) interfaces. If you've been following
uv's development, you've probably seen these new commands behind a preview flag. Now, the
interfaces are stable and ready for production-use.

These features are all documented in [new, comprehensive
documentation](https://docs.astral.sh/uv/).

This release also stabilizes preview functionality in `uv venv`:

-   `uv venv --python <version>` will [automatically
    download](https://docs.astral.sh/uv/concepts/python-versions/#requesting-a-version) the Python
    version if required
-   `uv venv` will read the required Python version from the `.python-version` file or
    `pyproject.toml`

The `uv pip` interface should not be affected by any breaking changes.

Note the following changelog entries does not include all the new features since they were added
incrementally as preview features. See the
[feature page](https://docs.astral.sh/uv/getting-started/features/) in the documentation for a
comprehensive listing, or read the [blog post](https://astral.sh/blog/uv-unified-python-packaging)
