Once tasks are tagged, the ``concurrentRestrictions`` setting sets
restrictions on the tasks that may be concurrently executed based on the
weighted tags of those tasks. For example,
weighted tags of those tasks. This is necessarily a global set of rules,
so it must be scoped `in Global`. For example,
::
concurrentRestrictions := Seq(

Tags.limit(Tags.CPU, 2),
Tags.limit(Tags.Network, 10),
Tags.limit(Tags.Test, 1),
