#This code replaces accents to normal chars(e.g "á" => "a"), everything that isn´t in "a-zA-Z0-9" to "", multiples spaces to one space, and one space to "-".
#This is useful to make URLs from titles, like Netscape.com does...
#"A new report recommends only work 4 -6 hrs a day" => #"A-new-report-recommends-only-work-4-6-hrs-a-day"
#"Video: \"Popular Mechanics\" editor debunks 9/11 myths" => "Video-Popular-Mechanics-editor-debunks-911-myths"
# etc..
# The code is 95% based on http://textsnippets.com/posts/show/451
