This is the build system for the blog commutative.group. The resulting code generated by this tool can be found at this repository. Following the name of the blog, this build system is named after Niels Abel.
Abel uses plasTeX.
To build PNGs for the algo and nalgo environment automatically you need PyMuPDF.
PDFCrop is also necessary but should come with your system.
Of course, working installations of TeX Live complete with latexmk are required.
