+       "This is the principal package in the AMS-LaTeX distribution.  It adapts
+for use in LaTeX most of the mathematical features found in AMS-TeX; it is
+highly recommended as an adjunct to serious mathematical typesetting in LaTeX.
+When amsmath is loaded, AMS-LaTeX packages @code{amsbsyamsbsy} (for bold
+symbols), @code{amsopnamsopn} (for operator names) and
+@code{amstextamstext} (for text embedded in mathematics) are also loaded.
+This package is part of the LaTeX required distribution; however, several
+contributed packages add still further to its appeal; examples are
+@code{empheqempheq}, which provides functions for decorating and highlighting
+mathematics, and @code{ntheoremntheorem}, for specifying theorem (and similar)
+definitions.")
