Look for files that match the specified pattern in the current build, then for each of them trigger a build of the specified project(s) by passing that file as a file parameter.

This implementation does not interpret the contents of those files, and instead it simply gets passed and placed into the workspace of the triggered project(s) under the name specified here.

This is useful, for example, when you have a portion of the job that can be split into concurrently executable subtasks. In such a situation, you can have an earlier step produce subtask work units by packaging necessary stuff into individual files, then use this mode to execute them all in parallel.
