# IFS is a special variable that controls splitting. We split on "|" and "=", not whitespace.
# "$*" will now become a string like a|b|c

# Split on | and =.  $* will insert the | itself when IFS="|", so we
# get back what we put in, except everything's now split on = too, i.e.
# "a b" "c" --option=file
# becomes
# "a b" "c" --option file


# Return IFS to its normal whitespace.

# Loop until all arguments are used up.
# Shift tosses the value of $1 and sets $1=$2, $2=$3, ...
# so doing this repeatedly will decrease the value of $# until
# we run out of arguments.
