The GNU/Linux operating system you are currently running is being developed
as free and open-source software.
This means it is contributed to by hundeds of thousands of individuals like you
who submit bug reports, patches, feature suggestions, or new source code.
Nowhere near perfect, it is a global, communal effort for the betterment
of the human society.
It also means it comes with four essential freedoms: the freedom to run it,
study it, modify it as you please, and pass it along.
