 The following wordsearch grid contains some Christmas words. Clues run either left-to-right or top-to-bottom. BUT: they've been encrypted! For each clue N+1, the grid is Vigenere-encrypted using clue N as the key. For example, the first two rows of the grid when decrypted with the key EXAMPLE would be: X R B X P Y A M M N I G V S S A E N I D B M D H U C The first clue is "CHRISTMAS". Find the next clue, and the next, and so on until you find CHRISTMAS in the grid. As a bonus, each clue has a RED HERRING somewhere else in the grid. T U B L A N W I P N W R K

Create a directory for the vagrant VM:

mkdir numbas_lti
