pdflatex error with fvextra and nimbusmono font

[Karl Berry]

    >>     !pdfTeX error: pdflatex (file fontools_ts1.enc): cannot open encoding

I added a dependency on fontools to nimbus15, which is the package which
actually contains the various fonts that use fontools_ts1.enc, as far as
I could see. Thanks for the report.

    I thought TeX Live is aware of collection-level dependencies.
    Isn't it the case any more?

Although we have said so, I'm afraid it has never been 100% true.

In this case, the fontools package is primarily about the font utility
programs it divides. It would not be right for it to be part of
collection-fontsextra, which are the actual fonts, which is a huge
collection, one of the most likely to be omitted.

And, on the other hand, I think it is only good to reuse pre-existing
.enc (or any other) files, as the nimbus15 author (thanks Michael) has
done here. So this particular dependency is unavoidably
cross-collection, as far as I can imagine. --best, karl.
