The directory 'latexdoc' contains a work-in-progress of DWARF5 in latex source. See latexdoc/README and tools/README and latexdoc/Makefile for more information. The tools directory is intended to help in overall reviews of the latexdoc files and for special projects involving the .tex files. The tools read the .tex source and operate on that source in various ways. Editting a .tex file and committing the result does not require or involve any use of the python or other code in the tools directory. Most contributors editting the .tex source have no need to look at the tools source or use the tools.
