#   The MacTex website (https://www.tug.org/mactex/uninstalling.html) says it's "difficult"
# to uninstall Ghostscript, as installed by MacTex. Their suggestion is to:
#     open the MacTeX-2015 install package and select "Show Files" from the resulting "File" menu of Apple's installer
# and then:
#     Find files related to Ghostscript and remove them.
# which is exactly what this script does. It also prints the names of the deleted files, and moves the files to
# the user's Trash instead of actually deleting them. This can help you roll back the effects of the script in
# case something goes wrong.
