Convert requires into a graph - this is pretty dreadful please can someone do better?

go.sh

egrep -e "require\s\"([a-z]|_|/)+\"" -o -r lib | ./sniffrequires.rb  | dot -Tsvg > /tmp/foo.svg; open /tmp/foo.svg

sniffrequires.rb

#!/usr/bin/ruby

puts "digraph {"
$stdin.each do | line |
  /lib\/(?<from>(\w|\/)+)(\.rb)?:require \"(?<to>(\w|\/)+)/i =~ line
  puts "\t #{from.gsub("/", "_")} -> #{to.gsub("/", "_")}"
end

puts "}"

To be fair, the parser version is possibly worse :D
