elif is short for "else if".  It will always check the first if, and
after that, it works it's way down the elif's only if the preceding
one fails (hence the "else").  It can be read as:

if the first condition is true,
then do this stuff;
else, if the second condition is true,
then do this other stuff,
else, if the third condition is true,
then do this other other stuff.
