How to upgdate the language file according to new v1.5.1 strings?

I am the Chinese language translator of AceSEF. Today I noticed that AceSEF v1.5.1 had changed almost ALL the language strings. When I check my old translation, it is only 6% valid.

I think, maybe you only changed the language variable (the part before the equal sign), the value (the part after the equal sign) may remain the same.

I hate to compare and update those strings manually.

Do you have any tool, or any rule for the language variable naming, to help me easily do the translation upgrade?

Thanks.
