   1 # This script treats the OS X pkg as an xar archive and uncompresses it to
   2 # the filesystem. The xar file contains a file called Payload, which is a
   3 # gziped cpio archive of the filesystem. It then cd's into the file system
   4 # and executes '$appname --version-and-path' and checks whether the output
   5 # of that command is right.
   6
   7 # If all of the paths listed therein are loaded from within the current PWD
   8 # then it exits with code 0.
   9
  10 # If anything goes wrong then it exits with non-zero (failure).  This is to
  11 # check that the Mac OS '.pkg' package that gets built is correctly loading
  12 # all of its packages from inside the image.
