DESCRIPTION="Structural search and rewrite tool for code using tree-sitter ASTs"
HOMEPAGE="https://ast-grep.github.io/ https://pypi.org/project/ast-grep-cli/"

# Upstream (maturin) publishes platform-tagged wheels containing the native
# ast-grep/sg binaries; the sdist is only a pip download wrapper with no Rust
# source. PyPI dist name is ast-grep-cli, wheel name uses an underscore.
