The Sky Environment

The main files loaded by the Sky environment are Sky files, though they can refer to binary resources like images and fonts.

Conventional MIME type: text/sky, though this type is neither necessary nor sufficient to indicate that a file is a Sky file; only the signature matters for type dispatch of Sky files.

Conventional extension: .sky
