### Diff Functions ###
-# Checks the difference between the content of the file with path "$1"
-# and the output of the CLI when called with the rest of arguments
-# to this function.
+# Checks the difference between:
+#
+# 1. What the CLI outputs on its standard output when given the arguments
+# "$@" (excluding the first two arguments).
+# 2. The file with path "$1".
+#
+# And the difference between:
+#
+# 1. What the CLI outputs on its standard error when given the arguments
+# "$@" (excluding the first two arguments).
+# 2. The file with path "$2".
#
# Returns 0 if there's no difference, and 1 if there is, also printing
# said difference to the standard error.
