echo This script has been written to anticipate some of the more common problems one might
echo encounter building ANY large, complex software package.  But it is not pefect, and
echo there are certainly some situations it could encounter that it cannot deal with
echo gracefully.  Altering the system configuration from something reasonably standard,
echo removing parts of the filesystem, moving system libraries around arbitrarily, etc,
echo it likely cannot cope with.  It is just a script.  It isn\'t intuitive or artificially
echo intelligent.  It tries to make life a little easier for you, but at the end of the day
echo if it runs into trouble, a certain amount of knowledge on your part about
echo system configuration and idiosyncrasies will inevitably be necessary.
