Awfully sorry, forgot to commit a typo fix;
and there is no need in `compatible' with GTK and Lesstif hids
arguments parsing.

BTW, it seems to me that it does not really changes the groups
visibility: I press Tab with `component' layer from the component
group active and see the same `component' above all; the pads
are shown from the right side, though. am I doing
something wrong? I stack the patches on top of current master.

Subject: [PATCH] Add SwapSides_nogui action

The action is similar to SwapSides, but it
depends on no real GUI, so can have effect when
running an exporter from command line or
with batch GUI.

+determines which solder mask you see.
+
+As a special case, if the layer group for the side you're looking at
+is visible and currently active, and the layer group for the opposite
+is not visible (i.e. disabled), then this action will also swap which
+layer group is visible and active, effectively swapping the ``working
