Hello all
I want to convert a tex file into a pdf by using pdflatex. For that, I thought 
the 'subprocess' module might be a good option. My code doesn't work at all tho:

Import os, subprocess

def main():
        scriptpath = os.path.dirname(__file__)

        p = subprocess.Popen("pdflatex --include-directory=%s 
--output-directory=%s/output --aux-directory=%s/temp --interaction=nonstopmode            
                                        myFile.tex"
                             % (scriptpath, scriptpath, scriptpath),
                             stdin=subprocess.PIPE,
                             stdout=subprocess.PIPE,
                             stderr=subprocess.PIPE,
                             shell=True,
                             cwd=scriptpath)
    (child_stdin,
     child_stdout,
     child_stderr) = (p.stdin, p.stdout, p.stderr)
    print 'stdin'
    print child_stdin
    print 'stdout'
    print child_stdout
    print 'stderr'
    print child_stderr

When I run that code I get the following printouts:

stdin
<open file '<fdopen>', mode 'wb' at 0x009E7968>
stdout
<open file '<fdopen>', mode 'rb' at 0x009E7A40>
stderr
<open file '<fdopen>', mode 'rb' at 0x009E79F8>
Done


Just a guess - but how about consuming the very verbose latex ouptut? 
Otherwise latex will stop when the stdout-pipe is full.

And beware of the interactive prompte of latex - that thing has bitten 
me more than once.
