12 oopptt--ccaassee..ppll reads a ttiinn(1) filter-file (ttiinn(5)) with regexp filters on
13 STDIN and turns all case insensitive regexp into case sensitive ones
14 whenever possible, as case sensitive regexp are (a bit) faster.
15
17 The case= line must come before any line with a regexp pattern, (that
18 is the order ttiinn(1) saves the filter file, if you created the filter by
19 hand and never let ttiinn(1) rewrite the file, you might want to check
20 that first).
21
22 Don't use oopptt--ccaassee..ppll on wildmat filters, transform them into regexp
23 filter via ww22rr..ppll(1) first.
