+SYNTAX
+        if (expr1) statement1;
+        else if (expr2) statement2;
+        ...
+        else if (exprN) statementN;
+        else statementX;
+
+DESCRIPTION
+        The if() statement implements the conditional execution of statements.
+        The expressions 'expr1' .. 'exprN' are evaluate in the order they
+        appear until one of the expressions returns non-0 ('true'). At that
+        point, the statement associated with the expression is executed, and
+        the program continues after the if() statement. If none of the
+        expressions evaluate to 'true', the statementX in the 'else'-branch
+        is executed.
+
+        Both the 'else if' branches and the 'else' branch are optional, and
+        there can be any number of 'else if' branches - but there must be one
+        'if' branch, and the branches must be in the order given above.
+
+        Any 'else' or 'else if' always relates to the immediately preceeding
+        'if' resp. 'else if' conditional. This means that
+
+          if (a)
+          if (b) do_b;
+          else do_c;
+
+        is interpreted as
+
+          if (a) {
+            if (b) do_b;
+            else   do_c;
+          }
