Babel, gnuplot, post processing

How can I perform post processing on eps files produced by gnuplot
source blocks? I want to take out the extra white space margins in the
eps file by running eps2eps utility on the eps file produced by
gnuplot.

I believe that if given a :file header argument the gnuplot block will
return the path to the altered file as it's return result.  You could
use a :var header argument to feed this path into a shell script code
block which could call eps2eps on the resulting file.

With this setup, every time the sh code block is evaluated it will call
the gnuplot code block before it is run.  See the relevant manual
chapter for more information.

The easiest solution (although maybe not the most elegant) is to do this
from within gnuplot.  I do something similar in that I process the eps
to create a pdf.

#+begin_src gnuplot :file xxx.pdf
  reset
  clear
  set output 'xxx.eps'
  set terminal postscript eps enhanced 18
  ...
  plot ...
  ! epstopdf xxx.eps
#+end_src

That is a better solution that what I was struggling with. Thanks.
