1pub mod ffi;

3/// Returns a formatted string representing the version, build profile, and target of the `gctex` crate.
4///
5/// This function makes use of several compile-time environment variables provided by Cargo
6/// to determine the version, build profile (debug or release), and target platform.
7///
8/// # Returns
9/// A `String` that contains:
10/// - The version of the `brres-sys` crate, as specified in its `Cargo.toml`.
11/// - The build profile, which can either be "debug" or "release".
12/// - The target platform for which the crate was compiled.
13///
14/// # Example
15/// ```
16/// let version_string = brres_sys::get_version();
17/// println!("{}", version_string);
18/// // Outputs: "riidefi/brres-sys: Version: 0.1.0, Profile: release, Target: x86_64-unknown-linux-gnu"
19/// ```
