I am trying to set up Texmaker, so I can use
biber seems already supported by
latexmk. I confess I do not understand how I should proceed about it.
latexmk, I am actually using this command line:
latexmk -e "$pdflatex=q/xelatex -synctex=1 -interaction=nonstopmode/" -pdf %.tex.
I have also created and modified the file
.latexmkrc as described in the list, but this should only work from the command line.
