A guard against empty `USE_SSL` - just tested without and it seems working
(probably because of the quotes) but I would not bet that this is the behaviour
in every shell...
If it was empty, and a shell executes this as `if [ $USE_SSL = ON ] ; then
echo "ON"; fi` then you'll get something like this: `bash: [: =: unary operator
expected`
