BIML language definition for SublimeText.
If you haven't already, install Package Control, then select Biml from the Package Control: Install Package dropdown list in the Command Palette.
To set this as your default Biml syntax, open a Biml file, then select View -> Syntax -> Open all with current extension as... -> Biml.
To turn on the Biml color scheme, select Preferences -> Color Scheme -> Biml -> Biml, which will show snippet (T4) block highlights and other highlighting.
