 Introduction
 ============
 
-The `astropy.utils` package contains general-purpose utility functions and
-classes.  Examples include data structures, tools for downloading and caching
-from URLs, and version intercompatibility functions.
-
-This functionality is not astronomy-specific, but is intended primarily for
-use by Astropy developers. It is all safe for users to use, but the functions
-and classes are typically more complicated or specific to a particuly need of
-Astropy.
-
-Because of the mostly standalone and grab-bag nature of these utilities, they
-are generally best understood through their docstrings, and hence this
-documentation does not have detailed sections like the other packages.
