Configuring Sublime Text

Sublime can run bemy through build system.
Autotask:

{
	"cmd": [ "bemy" , "-f", "${file}" ],
	"path": "/usr/local/bin/"
}

Task of creation for css file only:

{
	"cmd": [ "bemy" , "-f", "css", "${file}" ],
	"path": "/usr/local/bin/"
}

Unfortunately, sublime doesn't support user input in the build system, so you have to create build system for every needed situation.
