One question about the chgdiff.pl script

Message

The VASP developers supply some scripts about charge density. Now I have a question about the algorithm of chgdiff.pl usage:
chgdiff.pl (CHGCAR1) (CHGCAR2).
Does that means CHGCAR_diff = CHGCAR2 - CHGCAR1
or the reverse CHGCAR1 - CHGCAR2?

Note: I notice there is a description in the chgdiff.pl script written in Perl language.
usage: chgdiff.pl <reference CHGCAR> <CHGCAR2>\n

Thank you in advance for any confirmation.

It is CHGCAR2 - CHGCAR1
