Hi David,

I'm afraid you will just have to take my word for it :-)

SqueakMap is nice because it makes the packages easily findable,
but a long-standing annoyance is that I have no way of expressing
the version compatibility. The warnings from SqueakMap look alarming,
but I don't know how to fix that.

Bottom line: For any version of Squeak that has been released in
the last ten years or so, please use the latest version of OSProcess
and CommmandShell.

Dave
