Makefile should detect shell-escape option, needed by pgfplot/gnuplot

[GoogleCodeExporter]

If you use pgfplot with gnuplot in order to draw inlay graphics, pdflatex needs 
an additional command line argument (-shell-escape). It would be nice if the 
Makefile appends it automatically.

@see www.iro.umontreal.ca/~simardr/pgfplots.pdf page 34

I'm reading about pgfplots now.  Looks really interesting.

So, the -shell-escape is there because pdflatex wants to shell out to gnuplot 
to do its work, right?  Make makes this sort of thing really hard (global 
parameter settings based on the way that dependencies are set up).  I think we 
have basically two options:

1) Always set --shell-escape.  This seems like it could be dangerous, but I 
don't have my head wrapped around all of the implications.
2) Provide an externally-settable LATEX_OPTS variable, that you can set in 
e..g, Makefile.ini or Variables.ini like so:  LATEX_OPTS := -shell-escape

Thoughts?

I'd prefer the second option - seems more generic :D
A notable alternative to pgfplots is TiKZ, which works with pdflatex without 
any issues.

OK - try the attached.  It allows you to set "LATEX_OPTS" and add extra latex 
options to the command line, like the --shell-escape option you need.

You can put it into Variables.ini or Makefile.ini like this:

LATEX_OPTS := -shell-escape
