-// Yarn doesn't support concurrent access to its global cache,
-// i.e. parallel execution of several "yarn install" tasks,
-// since these tasks are independent, we can establish arbitrary total order
-// to prevent their concurrent execution.
-// Note that "task1.mustRunAfter(task2)" ordering has an effect only when both
-// tasks are scheduled for execution, therefore should be established between
-// all pairs of "yarn install" tasks to define their total order and to prevent
-// their concurrent execution even in case when one or more of these tasks not
-// scheduled.

 // by default, Yarn will update lock file if it is not up to date with "package.json"
 // using option "--immutable" will disable this behavior and "yarn install" will fail if lock file is out of date
 // all "yarn install" tasks should be executed with this option for reproducibility of builds
 // and to prevent developers from forgetting to update lock file when they update "package.json"
