LaTeXML-Plugin-Introspection
LaTeXML introspection for TeX package dependencies and command sequence dictionaries
To generate the full reports (in the default dictionary.json and dependencies.json files) run:
perl generate_reports.pl
To generate the reports for any subset of packages, simply supply them as arguments:
perl generate_reports.pl article.cls graphicx.sty tikz.sty
If this proves useful, and once the method is refined to be as efficient as possible, it might be advantageous to integrate this functionality in the LaTeXML web service.
