I think we should omit the filename argument entirely on the
command line, because in the Windows case we're going to need
to support generation of multiple output files. In such a case
passing a filename on the ARGV doesn't make sense.

I could see value in having an optional arg to specify a
filename prefix. eg

   # osinfo-install-script --prefix foo   win2k3r2

would result in a file  'foo-windows.sif' being created.

I think we could probably just make that an parameter flag
instead eg.

   # osinfo-install-script --output-dir /some/dir  win2k3r2

Given an an <install-script> will allow multiple <template> args
each with their own filename, I don't think it really makes sense
to have an 'output-filename' property.  I'd support having an
"output-prefix" property to support the usage I desribed earlier

This parameter appears to be ignored in this method which is strange ?
