#89 rawtowav does not have -h option

[Giulio Paci]

The attached patch adds a -h option to rawtowav.

While the program is not supposed to be directly used by users, still I think that if it is distributed and installed, it should have an help.

Hi,

Thank you for using SPTK and for reporting the problem.
We are investigating it.

The next major version got away from this kind of implementation. Let me close.
