  • This is an spkg, rather than a standard pip-installable package.
  • Version 0.1 contains modules on digital geometry, combinatorics on words and more.
  • Version 0.2 provides modules on multidimensional continued fraction algorithms, matrix cocycles, languages and tikzpictures.
  • Version 0.3 to be released will be pip-installable.
