Light LaTeX Make (llmk) is yet another build tool specific for LaTeX documents. Its aim is to provide a simple way to specify a workflow of processing LaTeX documents and encourage people to always explicitly show the right workflow for each document. You can describe the workflows either in an external file llmk.toml or in a LaTeX document source in the form of magic comments. It provides a uniform way to describe the workflows available for nearly all TeX environments, and behaves exactly the same in any environment. At this point, llmk intentionally does not provide any method for user configuration. Therefore one can guarantee that for a LaTeX document with an llmk setup, the process of typesetting the document will be reproduced in any TeX environment with the program.
