The setting will apply to any commands after it's set. Sourced files are
executed as if the lines appeared directly in the file sourcing them. Place
set -x and set + around any lines you want traced. You can use those
settings wherever and as many times as you want. Narrowing their range will
allow you to focus on areas of interest and limit the amount of output
where it's not needed.
