 Since the primary environment is typically the environment of a project you're working on, while environments later in the stack contain additional tools, this is the right trade-off: it's better to break your development tools but keep the project working. When such incompatibilities occur, you'll typically want to upgrade your dev tools to versions that are compatible with the main project.
 ### "Glue" packages and dependencies

-These are defined by adding the following two sections to a package's `Project.toml` file:
+A "glue package" is a module that is automatically loaded when a specified set of other packages (its "glue dependencies") are loaded in the current Julia session.

 OtherGlueDep = "862e..." # uuid

 ```
 
 The keys under `gluepkgs` are the name of the glue packages.
-They are loaded when all the packages on the right hand side (the glue dependencies) of the glue package are loaded.
