I found out how to get the Distribution of Linux, but it varies from
distribution to distribution, so it will take a little extra effort to
cover most of the bases.
I also looked into finding the window manager, and it does not seem as
clear cut as I expected. It is more complex than getting the name and
version of the Distribution. For now, this part will definitely be
user input, unless I find something simpler that what it now appears.
I'll update my Linux version of the clip soon.
Hope everyone has a great and safe Independence Day!
