This is a trivial merge sample text.
Branch A is expected to upcase this word, here.
There are some filler lines to avoid diff context
conflicts here,
like this one,
and this one,
and this one is yet another one of them.
At the very end, here comes another line, that is
the word, expected to be upcased by Branch B.
This concludes the trivial merge sample file.
