Usage of this script:
* rake commits : Check commit logs written with non-ascii chars,
but without the correct encoding settings.
Always report Non-ascii in subject line as error.
* rake pot : Print the summary of the update of git.pot file
* rake XX.po : Create or update XX.po from the git.po tempolate file
* rake check[XX.po] : Syntax check on XX.po
