  UPDATED for 2023 - Now much simpler. The old tricks are no longer needed.

  The following code makes an 800×600 canvas that is always as sharp as possible for the device.

To set up:

1. Clone this repo. (Or just copy serve.go into a folder on your computer).
2. cd into it, and run go build serve.go

You can now run the binary like this: ./serve --root="/path/to/directory"

But to make it easier, put this in your .bashrc:
