With PR #77 a note about dashes in the crate name was added in the docs. The note was of course an essential addition.

I propose going a step further and handling the dashes internally, during the parsing (parse_spec() function).
I believe this addition will save people time trying to debug the reason that the logging does not work as expected.
I myself lost some time on this, even though I had read the docs, and I had read about the need to replace the dashes.

I would also have provided a PR too, but currently I am failing to build the library (see #190 (comment)).

Is there a valid reason for not handling the dashes internally?
