<include> tag

The <include> tag enables you to import another roslaunch XML file into the current file. It will be imported within the current scope of your document, including <group> and <remap> tags. All content in the include file will be imported except for the <master> tag: the <master> tag is only obeyed in the top-level file.

Attributes

  ns="foo" (optional)

  • Import the file relative to the 'foo' namespace.
