[NTG-context] list of used files

Hi, is there some mechanism (directive?) that gives me a list of files that were involved in making a PDF? Preferably only those outside of the texmf trees, but I could filter that myself. (With "latexmk -recorder somelatexfile" I get the file list as a .fls file.) My goal is to commit all used images to my git repo, while I often have a big collection of images that I didn’t use in the end and don’t need in the repo. Hraban
