This is the Biopython DIST GitHub Repository at github.com/biopython/DIST using GitHub Pages to host biopython.org/DIST/ aka biopython.github.io/DIST/ which (on our original web-server) was a folder of static file for distributing our releases, and associated documentation. e.g. biopython.org/DIST/docs/tutorial/Tutorial.pdf aka biopython.github.io/DIST/docs/tutorial/Tutorial.pdf

If you are looking for individual Biopython releases, try downloads page or Biopython on PyPI.
