That will invoke the program. I'll probably try that.

One disadvantage there is the process won't have an informative name;
instead of being named ‘/foo/bar/lipsum’, it will be named ‘python’
which is less useful.

So, I'm still wanting to know from Setuptools itself at run time, what
filesystem path Setuptools installed the command to.
