From: Leonardo Sandoval <[email protected]> By default, exports the whole workspace (all recipes) including the source code. User can also limit what is exported with --included/--excluded flags. As a result of this operation, a tar archive containing only workspace metadata and its corresponding source code is created, which can be properly imported with 'devtool import'.
