 ```

+#Using in command line
+
+`cargo install svgbob`
+
+`svgbob` normally operates on stdin and stdout:
+```console
+$ svgbob < examples/long.bob > long.svg
+```
+produces an SVG in `long.svg` similar to the one produced by the old `main` binary. `svgbob` also allows passing arguments instead:
+```console
+$ svgbob examples/long.bob -o long.svg
+```
+And you can mix and match:
+```console
+$ svgbob -o long.svg < examples/long.bob
+$ svgbob examples/long.bob > long.svg
+```
+
+This is also documented in the output of `svgbob --help`:
+```console
+$ svgbob --help
+svgbob 0.1.2
