-`./demo.exe` (or `./result/bin/buchstabensuppe-demo` if you use nix)
-renders a string using `libbuchstabensuppe` and prints a preview
-to `stdout`. it supports usual opentype and truetype fonts, but
-won't support e. g. colored fonts.
+if you want to play around with the font rendering in binary
+mode you can use the dry run mode of the supplied `./bs-renderflipdot.exe`

-good results for the rendering target (16px font size, no grayscale)
-can be achieved with gnu unifont:
+Run `./bs-renderflipdot.exe -?` for usage instructions and don't forget `-n`
+for dry running!
