## createdist.sh
## This is a shell script to automatically create a gnuplot distribution 
## for Mac OS X. It will download and build a source tarball and create
## a disk image with a standard GUI installer and folders with supporting
## files (ReadMe, docs in PDF and demos).
##
## The utility "freeze" from the application Iceberg is required, see
