-If feature FEATURE is not loaded, load it from FILENAME.
-If FEATURE is not a member of the list `features', then the feature
-is not loaded; so load the file FILENAME.
-If FILENAME is omitted, the printname of FEATURE is used as the file name.
-If optional third argument NOERROR is non-nil, then return nil if the file
-is not found instead of signaling an error.
+Ensure that FEATURE is present in the Lisp environment.
+FEATURE is a symbol naming a collection of resources (functions, etc).
+Optional FILENAME is a library from which to load resources; it defaults to
+the print name of FEATURE.
+Optional NOERROR, if non-nil, causes require to return nil rather than signal
+`file-error' if loading the library fails.
+
+If feature FEATURE is present in `features', update `load-history' to reflect
+the require and return FEATURE.  Otherwise, try to load it from a library.
+The normal messages at start and end of loading are suppressed.
+If the library is successfully loaded and it calls `(provide FEATURE)', add
+FEATURE to `features', update `load-history' and return FEATURE.
+If the load succeeds but FEATURE is not provided by the library, signal
+`invalid-state'.
+
+The byte-compiler treats top-level calls to `require' specially, by evaluating
+them at compile time (and then compiling them normally).  Thus a library may
+request that definitions that should be inlined such as macros and defsubsts
+be loaded into its compilation environment.  Achieving this in other contexts
+requires an explicit \(eval-and-compile ...\) block.
