It guarantees the relevant feature is available, generally as a side effect
of loading the named package. I believe the package much "provide" its
name. If not found, an error is raised. Full details can be found here:

While under the covers I imagine the implementation is much different, I my
mental model is similar to Python's import statement or C++'s namespace
statement. All three make a series of names available to you, though
require is a global operation, not local to a particular module or
translation unit.
