OPT-CASE(1) Optimize case insensitive regexp filters OPT-CASE(1)
opt-case.pl - Optimize case insensitive regexp filters for tin
opt-case.pl < input [> output]
opt-case.pl reads a tin(1) filter-file (tin(5)) with regexp filters on
STDIN and turns all case insensitive regexp into case sensitive ones
whenever possible, as case sensitive regexp are (a bit) faster.
The case= line must come before any line with a regexp pattern, (that
is the order tin(1) saves the filter file, if you created the filter by
hand and never let tin(1) rewrite the file, you might want to check
Don't use opt-case.pl on wildmat filters, transform them into regexp
filter via w2r.pl(1) first.
