No ... you don't need ssg.

If you only need to get some stuffs published, you don't need a static
site generator at all.

A dozen lines of bash script would do...

scripts/gen.sh  - gives you site/directory index
m4              - gives you text template and macros [1]
plain txt       - gives you everything else
