[Swift-devel] Example of wrapper staging?

[Yadu Nand Babuji]

Hi Mike,

The schema is here swift-k/resources/swift.conf.schema, and I do see 
this wrapperStagingLocalServer
defined in the schema.

Here's a github link to the schema : 
https://github.com/swift-lang/swift-k/blob/master/resources/swift.conf.schema
