// Package modfile implements parsing and formatting for go.mod files.
//
// This is now just a simple forwarding layer over golang.org/x/mod/modfile
// apart from the ParseGopkgIn function which doesn't exist there.
//
// See that package for documentation.
//
// Deprecated: use [golang.org/x/mod/modfile] instead.
