For the variables which are only used once, just put them directly in the
strings below.

[no longer working on chromium, 2013/02/20 14:43:38]

Only sig_files and outfile_type are used once, I hope it is fine to put them as
variables to help readability.

Is .. necessary for this?

[no longer working on chromium, 2013/02/20 14:43:38]

We need to include the output_root since the header pulse_stubs.h is locating
there. But not ..

These shouldn't be necessary here since you're in target.
