# We use 'find' to get the .bom files under the .pkg folder
# and then run 'lsbom' on them
# and then use 'sed' to remove the extraneous dot from the start of each line
# and run the results through 'sort | uniq'
# (this is useful since there are often two duplicate bom's in a .pkg)
# and then use 'grep' to narrow it down to files or folders that are
# directly under /Applications or /Applications/Utilities
