Re: gEDA-user: Adding power/ground plane after traces

If your previously laid-down tracks didn't have the clear flag set,
you can at least edit the .pcb file and add the "clearpoly" flag to
all the lines.

You can use the J key to selectively un-join lines, or Shift-J for
selected lines, but as it's a toggle, you can't just select *all* and
apply it, as it will re-join previously unjoined lines.

You can select all and do :SetFlag(SelectedLines,join)
