support/graph-depends: add option to specify output file
Currently, graph-depends outputs the dotfile program to stdout, and uses stderr to trace the dependencies it is currently looking for. Redirection was done because the output was directly piped into the dot program to generate the final PDF/SVG/... dependency graph, but that meant that an error in the graph-depends script was never caught (because shell pipes only return the final command exit status, and an empty dot program is perfectly valid so dot would not complain). Add an option to tell graph-depends where to store the generated dot program, and keep stdout as the default if not specified. Signed-off-by: "Yann E. MORIN" <yann.morin.1998@free.fr> Cc: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Cc: Samuel Martin <s.martin49@gmail.com> [Thomas: rename metavar from DOT_FILE to OUT_FILE for consistency with the rest of the new option naming.] Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
