+# astcopy
+
+Package astcopy implements Go AST reflection-free deep copy operations.
+
+## Installation:
+
+```bash
+go get github.com/go-toolsmith/astcopy
+```
+
+## Example
+
+```go
+package main
+
+import (
+	"fmt"
+	"go/ast"
+	"go/token"
+
+	"github.com/go-toolsmith/astcopy"
+	"github.com/go-toolsmith/astequal"
+	"github.com/go-toolsmith/strparse"
+)
+
+func main() {
+	x := strparse.Expr(`1 + 2`).(*ast.BinaryExpr)
+	y := astcopy.BinaryExpr(x)
+	fmt.Println(astequal.Expr(x, y)) // => true
+
+	// Now modify x and make sure y is not modified.
+	z := astcopy.BinaryExpr(y)
+	x.Op = token.SUB
+	fmt.Println(astequal.Expr(y, z)) // => true
+	fmt.Println(astequal.Expr(x, y)) // => false
+}
+```
