Hi, folks, this is my first message and for precaution, I apologize in advance in case of messaging out place.
I work with e-books since 2009 and now I'm working on a translation of the epubcheck error messages.
Calibre has a lot of these messages translated for portuguese and I don't wanna use other technical terms, I prefer to use the existing technical terms to avoid confusion.
So, I'm digging the code for the file where the validator keeps its messages and solutions (and its translations).
Would someone indicate the file or folder where it resides?
Thanks in advance
