+Starts a "workspace group", a virtual folder to contain one or more projects.
+
+```lua
+group("name")
+```
+
+### Parameters ###
+
+`name` is the name of the virtual folder, as it should appear in the IDE. Nested groups may be created by separating the names with forward slashes.
+
+### Applies To ###
+
+Workspaces.
+
+### Availability ###
+
+5.0 or later.
+
+### Examples ###
+
+```lua
+workspace "MyWorkspace"
+
+-- put the projects "Tests1" and "Tests2" in a virtual folder named "Tests"
+
+group "Tests"
+
+    project "Tests1"
+      -- Tests1 stuff goes here
+
+   project "Tests2"
+      -- Tests2 stuff goes here
+
+-- Any project defined after the call to group() will go into that group. The
+-- project can be defined in a different script though.
+
+group "Tests"
+
+    include "tests/tests1"
+    include "tests/tests2"
+
+-- Groups can be nested with forward slashes, like a file path.
+
+group "Tests/Unit"
+
+-- To "close" a group and put projects back at the root level use
+-- an empty string for the name.
+
+group ""
+
+   project "TestHarness"
+```
+
+The group value is latched the first time a project is declared but it can be overriden later:
+
+```lua
+local prj = project "Tests1"
+prj.group = "NotActuallyATest"
+```
+
+or
+
+```lua
+project("Tests1").group = "NotActuallyATest"
+```
