I wanted a really simple static blog generator, and couldn't find a good, easy, simple solution that didn't depend on a million of other things.
This is a solution I've whipped up for my own personal use, hence why it's not really oriented towards multiple contributors, etc.
It's probably worth also adding that this has not been tested on macOS or Windows, so you might encounter issues on those platforms—but generally there shouldn't be any issues compiling for those if you so desire. It also depends on a few GNU extensions, so you're best off compiling it with GCC/Clang.
I'm making it public here just on the off-chance it might be useful to anyone else. The contents under the test directory should give an idea as to how it all works.
