How to delete lines containing a given string?

Just like last week, where we wanted to replace a string, we can use sed for this task:

sed '/pouet/d' file.txt

This will output file.txt on stdout without the lines containing pouet.

/*
  I've wrapped Makoto Matsumoto and Takuji Nishimura's code in a namespace
  so it's better encapsulated. Now you can have multiple random number generators
  and they won't stomp all over eachother's state.
  
  If you want to use this as a substitute for Math.random(), use the random()
  method like so:
  
  var m = new MersenneTwister();
