<em>v.parallel</em> creates parallel lines to the input vector lines which
can be used as half-buffers.
+<h2>NOTES</h2>
+Usage of <b>-b</b> flag will overrule the <b>side</b> parameter.
+
+<h2>BUGS</h2>
+There is a problem with side-offset parallel line generation for inside corners.
+To avoid this problem, the <b>-b</b> flag might be used.
+<!-- in Vect_line_parallel(), v.segment is also affected -->
