 * Eigth version. Added a new module SoXBasics1 where all the functions (contrary to the SoXBasics module) try to replace
 the initial file with the resulting one. Changed the lower bound for SoX "sinc" effect. Added help messages and version information
 being obtained in the command line.

+
+* Ninth version. Changed the behaviour in case of giving information to the user. Changed killing the main thread to raising a special
+exception with 'catchEnd' function. The program now becomes also a dependency for mmsyn7h package.
