Rotate text.
Rotate text clockwise or counterclockwise by pi/13 radians. The
direction is determined by number of command line arguments:
ruby entry.rb < input.txt > clockwise.txt
ruby entry.rb input.txt > counterclockwise.txt
cat input.txt | ruby entry.rb - > counterclockwise.txt
Rotating entry.rb clockwise produces a rot13 filter, rotating
counterclockwise produces a ruby program that outputs a rot13 message.
To decode the embedded message:
ruby entry.rb < entry.rb > rot13.rb
ruby entry.rb entry.rb | ruby | ruby rot13.rb
entry.rb also includes a brainfuck program.
