gEDA-user: strange lines at the end of gerber files

[Kai-Martin Knaak <kmk@xxxxxxxxxxxxxxx>]

On monday the first gerbers made with pcb from the current iso image will
go to the fab. I appreciate, that the layer commands have been  reworked.
No more identical layer names, no need to apply my renaming sed script :-)

While looking at the gerbers, I notice that there is an additional layer
at the end of files called *group*.gbr. Layer name is the same as further
up in the file "_C1". There is a LPC command in the next line. And the last
line of the file is crowded by a host of G commands without X or Y
parameters.  

Example: 
-----------------------------8<--------------
G54D25*%LNGROUP0_C1*% 
%LPC*%
G54D37*G54D36*G54D37*G54D38*G54D13*G54D38*G54D13*G54D38*G54D37*G54D13*G54D38*G54D36*G54D19*G54D39*G54D19*G54D39*G54D19*G54D39*G54D19*G54D39*G54D19*G54D39*G54D19*G54D11*G54D19*G54D11*G54D19*G54D39*G54D19*M02*

---------------------------->8----------------

What is the significance of these lines? gerbv didn't seem to care if I
removed them. Can I or should I remove them before sending the gerbers to
the fab?
