Hi David,

Here's an idea I thought of while watching the videos. If you want to
pre-populate the "Scheme executable" field in your Mosaic Instance Manager,
and you know that you're looking for a program called 'snd', then you
could use an OSProcess hack like this:

pathToExecutable: programName
	"Answer path to the a program, or empty string if not found"
	rs := (OSProcess outputOf: 'type ', programName) readStream.
	[rs atEnd or: [rs peek = FileDirectory pathNameDelimiter]]
		whileFalse: [rs next]. "skip leading verbiage"
	^ rs upTo: Character lf. "and trim trailing <lf>"
