I think the usefulness comes from developers wants to see what are the
modules are using by the running kernel in formatted way. 

This is very simple way to enlist all the modules with descriptions of
it.So , they can easily parse it with other scripts.

I believe you have already copy and paste the single line on your
terminal to see the output it produces, if not, I have already sent a
mail which includes the out of it.

If and only if, no other tool or mechanism(which might have skips my
eyes and knowledge) to find and display information this way.

Kindly, share me the other way , you can achieve that. This is a generic
script,and expecting stuff in common place, so everybody can use it.No,
special requirement is needed.

Here is little output,if you missed my other mail with it...

filename:/lib/modules/5.4.1-arch1-1ArchLinux-5.4.1/kernel/drivers/usb/host/xhci-pci.ko.xz
description:    xHCI PCI Host Controller Driver
depends:        xhci-hcd

These output can be parse by other scripts too(cliche...sorry) ..

Thanks,
Bhaskar
