boo hoo. there are very valid uses of copied code, or extremely similiar code (copy & paste and change a few things). we have that many times in the tree. the enforced indentation is completely nuts. i purposefully indent extremely incorrectly when adding debug code that i intend to remove again, to spot it faster. just one example, there are many more. python doesn't solve a problem. perl's been there already. oh, and the 80s sed, i use it a lot. as well as shell scripts. -- Henning Brauer, h...@bsws.de, henn...@openbsd.org BS Web Services, http://bsws.de Full-Service ISP - Secure Hosting, Mail and DNS Services Dedicated Servers, Rootservers, Application Hosting
