The homepage promises

I searched https://www.gerd-neugebauer.de/software/TeX/BibTool/bibtool.pdf for "check", but I only found "Semantic Check"

Use case:

I want to validate a .bib file and have the issues found output in a way. Maybe errorformat

What's wrong with the error messages of BibTool?

I think the message points to the exact place and should clearly depict what's wrong.

I see that the BibTool manual does not contain a list of error messages. But you can find some of them in the test file test/parse.t
