The package provides a script that performs ‘on the fly’ downloads of missing packages, while a document is being compiled. (This feature is already available in the MikTeX distribution for Windows machines.)

To use the script, replace your (LaTeX) compilation command with texliveonfly.py file.tex (default options are --engine=lualatex and --arguments="-synctex=1 -interaction=nonstopmode", which may all be changed).

The script is designed to work on Linux distributions.
