I am using tex4ebook to convert a .tex project into an .epub
I use a command like the following:
tex4ebook -d output -f epub3+latexmk_build -x book
My problem is that the leaves my directory littered with a host of temporary and auxiliary files. This is obnoxious, and I'd like to have all of those files stored in some sort of build directory. When producing a PDF, I do this using latexmk's -output-directory option but the similar option for tex4ebook only changes the location of the final epub not all the auxilary files.
Is there way to do this?
