You can use the .include environment dot command to import variables from
a different environment. To use it, create a variable named
".include" in
an environment, and set its value to the name of a different environment.
When the original environment is used in a project, the referenced environment's
variables are set as well.
Note: You can use more than one .include
variable in a environment, to include as many other environments
as desired. You can use this feature to create nested sets of variables, or
to manage a variable in a single location yet use it within many other environments.
