# Low-level bindings for PROJ v7.0.x
**This is a [`*-sys`](https://doc.rust-lang.org/cargo/reference/build-scripts.html#a-sys-packages) crate; you shouldn't use its API directly.** The [`proj`](https://github.com/georust/proj) crate is designed for general use.
A guide to the functions can be found here: https://proj.org/development/reference/functions.html. Run `cargo doc (optionally --open)` to generate the crate documentation.
# Requirements
This crate tracks the **latest stable release** of `PROJ`.
PROJ `v7.0.x` must be present on your system. While this crate may be backwards-compatible with older PROJ 6 versions, this is neither tested or supported.
