Wasn’t sure where to post this, but I noticed while reading through the “Compile them resources” article at http://www.haiku-os.org/documents/dev/compile_them_resources that the body of the article is duplicated. Not sure if that’s a website bug or a bug with the article 
I’ve made a ticket on trac for you.
You can view it here: http://dev.haiku-os.org/ticket/4575 .
This should be fixed now.
