If a file, like ooenv, is intended to be sourced, that means that the
commands in it are to be executed by the very shell that is sourcing
it, as the point with them is to affect the environment of that shell.
Running it as a command, i.e. a separate process, which is what
./ooenv would mean, is totally pointless.
