//! Build script for the Zep Key-Value Store library.
//!
//! This build script extracts the package name from Cargo.toml and makes it
//! available as a compile-time environment variable. This allows the library
//! to create storage directories and registry keys using the actual package name.

/// Main build function that sets up compile-time environment variables.
///
/// This function:
/// 1. Reads the current package information from Cargo.toml
/// 2. Extracts the package name
/// 3. Sets `ZEP_KVS_APP_NAME` as a compile-time environment variable
///
/// The `ZEP_KVS_APP_NAME` variable is used throughout the library to create
/// platform-appropriate storage paths.
