-		<title>Statements</title>

-			Statements represent actions to be performed. They can alter control flow (return, jump

-			rejecting a packet, etc.
-		</para>
-		<para>
-			Statements exist in two kinds. Terminal statements unconditionally terminate evaluation
-			of the current rule, non-terminal statements either only conditionally or never terminate
-			evaluation of the current rule, in other words, they are passive from the ruleset evaluation
-			perspective. There can be an arbitrary amount of non-terminal statements in a rule, but
-			only a single terminal statement as the final statement.

-			When an error is detected, nft shows the line(s) containing the error, the position
-			of the erroneous parts in the input stream and marks up the erroneous parts using
-			carrets (<literal>^</literal>). If the error results from the combination of two
-			expressions or statements, the part imposing the constraints which are violated is
-			marked using tildes (<literal>~</literal>).
-		</para>

-			For errors returned by the kernel, nft can't detect which parts of the input caused
-			the error and the entire command is marked.
