ChangeLog:
+ version 0.9.3 2014-04-21 - fixed transposition problem:
+ If song began in E-minor and signature is changed in half of song to A-minor
+ transposition must be omitted.
version 0.9.2 2013-12-13 - fixed: stop processing when pmxab fail.
- - Do not remove file pmxaerr.dat.
+ - When pmxab is called generated file pmxaerr.dat is not removed.
version 0.9.1 2013-12-09 - added some options. Improved processing.
