Quick update on evaluation of BLIS for 'foss' toolchain

Revamp of EasyBuild documentation

  • https://docs.easybuild.io
  • current status
    • hosted on readthedocs.io
    • .rst format (rendered by Sphinx)
    • some stuff is missing:
      • using a custom module naming schemes
      • writing easyconfig for (bundles of) Python package(s)
    • some pages in dire need of a refresh/update
      • pip install should be highlighted as recommended way of installing
  • EasyBuild tutorial (https://easybuilders.github.io/easybuild-tutorial) not integrated in current documentation
  • mkdocs is a way better tool
    • easier to work on documentation locally, trivial to get (live) preview of changes
    • also supported by readthedocs.io
    • .md (Markdown) format, so requires "porting" of .rst documentation
  • working group to revamp docs + port to mkdocs?
