No worries.  swipl[.exe] will stay as it is.  The app does allow
you to install it anywhere or run it directly from the disk
image.  Just add the Apps Contents/MacOS dir to your $PATH and
your are done.  With the advantage that you do not need admin
rights and don't even need to install it.

See my response to Paulo.

A notion of a working directory is there anyway.  I give some of this
a thought.
