Use this command-line script when you feel you have too much lib32 packages installed and you want to cleanup your system.
Ok, but how does it work?
Each time you run it, it will look for lib32 packages currently marked as "installed as dependency for another package" in the "Install Reason" (pacman -Qi <pkg>). If listed packages are desnecessary, it will uninstall them, with user's approval.
You'll probably want to run this script more than once, as some lib32 might be not necessary anymore after uninstalling another one.
P.S.: packages not marked as "installed as depedency" will not be listed neither removed.
Cleanlib32 is good! Thanks.
