#         USAGE:  ./total_linked_size.sh 
# 
#   DESCRIPTION:  (MacOSX only) This program tries to determine the
#                 total size of all the linked libraries that an
#                 executable uses. It requires that you first run
#                 the program through ktrace to get a ktrace.out file
#                 It doesn't add the size of the application binary itself
#                 to the total and it possibly includes system libraries
#                 in the total count
