# This package is ultimately built from the same source tree as uv, i.e.
# https://github.com/astral-sh/uv, and belongs to the same cargo workspace.
#
# The PyPI sdist includes a small subset of the same workspace crates as uv.
# (Note that these are not published on crates.io, and are neither intended for
# separate distribution nor suitable for separate packaging.)
#
# We choose not to build uv-build from the uv source package because this spec
# file can be much simpler than the one for uv, because the separation helps to
# keep track of which patches, licenses, additional sources, etc. apply to
# uv-build, and because – while it normally makes sense to synchronize updates
# of this package with uv updates – there will likely be times when we want to
# keep updating uv (primarily a developer tool) while holding uv-build
# (primarily used for building packages) at an older version for compatibility.

# For the foreseeable future, uv must use a fork of pubgrub (and the
# version-ranges crate, which belongs to the same project), as explained in:
#   Plans for eventually using published pubgrub?
#   https://github.com/astral-sh/uv/issues/3794
# We therefore bundle the fork as prescribed in
#   https://docs.fedoraproject.org/en-US/packaging-guidelines/Rust/#_replacing_git_dependencies
# Note that uv-build currently only uses version-ranges, not pubgrub.

# We will not be packaging an alpha version of rust-ron. We can adjust this
# after ron 0.9.x is released.
