STDIN and ARGF are both IOs. STDIN reads from the standard input. ARGF 
reads from the standard input and file names that are in ARGV.

IO#gets returns one line with a \n at the end or nil when there are no 
more lines available.

There's also IO#read which returns the whole file as a String and 
IO#readlines which returns the whole file as an Array of lines. (Each 
with a \n at the end.)
