// Package cgofreesqlite package provides a CGO free implementation of the sqlite3 driver. This wraps the
// modernc.org/sqlite driver and adds the PRAGMA foreign_keys = ON; statement to the connection
// initialization as well as registering the driver with the sql package as "sqlite3" for compatibility
// with entgo.io
//
// NOTE: This does come with around a 30% performance hit compared to the CGO version of the driver.
// however it greatly simplifies the build process and allows for cross compilation.
