Uninstall Ghostscript that comes with MacTex

uninstall-ghostscript.sh

#!/usr/bin/env bash

#   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.

# Note that this requires write access to the /tmp directory on your computer.

# Example usage:
#  You saved "mactex-20150613.pkg" in ~/Downloads and used that to install MacTex.bash uninstall-ghostscript.sh

#   This script comes with ABSOLUTELY NO WARRANTY WHATSOEVER. By running it, you agree to take full responsibility
# for anything that happens to your computer as a result.

#   At the end of the day, you should have deleted the files:
