Authors are not forced to use the clang-format setting, but should
atleast be inspired by the style.
The only thing which is now not allowed are tabs for ident/alignment!
Has no practical effect, but tells the compiler not to issue a warning
if the following variable in a function or program definition is will
not be used. The compiler will instead issue a warning if the given
variable is used.
Example:
program onremovescript( character, container, unused item, unused item_amount, movetype )
<some code here...>
endprogram
function myfunc( parameter1, unused parameter_for_future_use )
<some code here...>
endfunction
