I have to use a command line order to merge two pdf's, 'pdftk...'. I
have a controller that creates and returns the original pdf, but
instead of that i need to write the pdf to some place, then execute
the command and return the result.

I've been searching for help in the group and in the documentation but
i'm not able to guess anything. My code looks like this:

[...]
# Creamos el documento
fichero = StringIO.StringIO()
documento = CrearPDF(fichero, u'...)
[...]
documento.guardar()
pdf = fichero.getvalue()
fichero.close()
pylons.response.headers['Content-Type'] = 'application/pdf'
pylons.response.headers['Content-Disposition'] =
'attachment;filename=informe.pdf'
return(pdf)

Anyone can help me? The idea is write down the file to a 'temp' folder
and then return the result of the command, deleteing everything after.

Thanx in advance.
