Ruby doesn't support as many regex flags as Perl does.
This is good.
However, %r{..}i will do case insensitive; %r{...}x will do extended.There is a %r{...}m flag, but it doesn't *quite* do the same as somepeople expect, I think (it just changes the meaning of . to be able tomatch \n, etc. I think). There is no %r{...}g flag, IIRC.
If you simply want a match, you use "string" =~ /regex/options; if youwant to scan something, you might use #grep.
