quick question to any "pcb" users (open source geda tools):

I have a layout completed and I tried to create a copper pour with the
"rectangle" function but realized that my default clearance of 10 mil
(traces) is wayyy too small.

I believe its possible to change this individually (by clicking on each
trace) but is there a way to change this setting FOR ALL TRACES at once?
do I have to edit the layout file under VIM or is there an easier way?

thanks

Select -> Select All Objects

:ChangeClearSize(selected,+10,mil)
:ChangeClearSize(selected,=2,mm)

The command line window (":") allows a lot of flexibility, but you
need to read the "Action Reference" appendix of the manual to know
what to type in.

http://pcb.sourceforge.net/pcb-cvs/pcb.html#Action%20Reference
http://pcb.sourceforge.net/pcb-cvs/pcb.html#ChangeClearSize%20Action

Note that pcb's plugin system hooks into the command line, so if you
need something that's not already there, it's pretty easy to write a
new module, put it in ~/.pcb, and invoke it from the command window.

thanks man.
I read about this briefly some months back. After post, I am going now
reread that section of the manual.
