This challenge is a fun take on classic cryptography exercises.
Normally you're given an encrypted filler text, poem or something more
informational, but this time the plaintext is space-separated Perl
keywords that when interpreted print the flag.  The included Perl
script will translate the ciphertext by doing a monoalphabetic
substitution, then eval it for you.

My approach was attacking it one word at a time.  `qq` is the most
unique keyword to start with, `qx` came next, then I started finding
patterns and confirming them by searching the keyword list.  To
display my progress I changed the code to `print($text)` instead of
`eval($text)`.
