particlar it looks for the `NAME:' tag, either with a colon, or alone
on a line. Then `NAME:' must be followed by the routine name on the
same or the next line. When KEYWORD is non-nil, looks first for a
-`KEYWORDS' section. It is amazing how inconsisten this is through
+`KEYWORDS' section. It is amazing how inconsistent this is through
some IDL libraries I have seen. We settle for a line containing an
upper case \"KEYWORD\" string. If this line is not found we search
for the keyword anyway to increase the hit-rate
