As a user of unix variants, the concept of a self extracting
& executing file makes me uncomfortable.
The InstallAnywhere script is poorly written and because of
this it is absorbing a significant portion of my time. Unlike the
ms/apple masses the unix crowd is savy and understands OS
fundamentals; this creates a situation where "auto install" options
and whatnot are generally viewed negatively, and deep procedural
explanation and documentation are revered.
