I'm looking at static site (blog) generators, and what features would be useful.
LaTeX or Mathjax equation support.
Footnote / endnote support.
Something vaguely resembling a wiki.
Git / Gitlab
Makefile-instrumentable.
Markdown (possibly other LWML), preferably pandoc-flavoured.
SSH/SCP transport.
Bulk seeding / extraction
RSS/Atom
The first few of those are more specific.
