     5  // The txtar-goproxy command runs a Go module proxy from a txtar module
     6  // directory (as manipulated by the txtar-addmod command).
     7  //
     8  // This allows interactive experimentation with the set of proxied modules.
     9  // For example:
    10  //
    11  //	cd cmd/go
    12  //	go test -proxy=localhost:1234 &
    13  //	export GOPROXY=http://localhost:1234/mod
    14  //
    15  // and then run go commands as usual.
