# dirname gives you the path portion of the provided argument (removing the file name).
#
# This command gets the script's source file pathname, strips it to just
# the path portion, cds to that path, then uses pwd to return the (effectively)
# full path of the script. This is assigned to the variable. After all of
# that, the context is unwound so you end up back in the directory you started
# at but with an environment variable containing the script's path.
