Woo-hoo! I finally managed to finish a prototype of my static site generator!
I am still not entirely sure how it works with multiple pages, and there are missing features left to be done, but it converts its own README, so I'm happy with that.
Tomorrow, I'm planning to get a "demo" of sorts (probably its own documentation) working, and maybe work on how some planned optimizations might work. After all that, it should be usable, if buggy and weak in some areas.
