It looks mostly correct, although it is not sure yet if the utility
will be standalone-only or callable with csound -U (the latter case
increases Csound memory usage even when atsa is not used, but also
allows for use of the utility through the API e.g. from GUI frontends).
Also, the parameters could be referenced by the actual command line
flags, rather than numbers (the numbers were there only because I
copied the documentation from the ATSH html manual). Finally, the
preferred extension of the analysis output files is ".ats", and not
".apf" (the latter is for parameters saved by the GTK frontend).

Note: in the current version, spaces are apparently not allowed
between flags and values, so you need to use -b10 instead of -b 10.
